It is customarily not appropriate to ask for royalties on logo usage.
Traditionally all rights are transferred to the client in logotype projects and the designer retains nothing. I've never, ever, ever heard of any designer trying to limit the usage of a logo designed for a client. That's simply not done in my experience.
It's their logo and they need to ...

On many of the stock photo sites, you can generally obtain the watermarked version of the image for free. The idea is that you wouldn't use the watermarked version in production and that it's simply just for the mock-ups. For the final version of your design, that will head to production, you would then purchase the non-watermarked versions and then replace ...
You're in a bind in this kind of situation. You would probably be best to avoid stock photography completely.
Realize that you're going to be working mostly for free. Even if you win a few, the payouts in these "contests" are painfully low. Averaged across all your entries that don't win plus the few that do (even top talent on these sites runs about 1 in 8)...
Just to get this off the unanswered list, and since my comment appears to have been useful:
Most of the actual typographical requirements listed in this question will be matched by most fonts on the market; there are just one or two deal-breakers that are largely type-dependent:
Serif fonts rarely have single-storey g’s (except sometimes as an alternate)
Pearsonartphoto mentioned several raster formats. A couple of other file formats that are used for vector based files:
SVG (open standard) http://en.wikipedia.org/wiki/Scalable_Vector_Graphics
PDF (originally proprietary, now open standard) http://en.wikipedia.org/wiki/PDF
99.99999% of Royalty free stock image sites will allow for the download of 72ppi images, but then you traditionally open the image in Photoshop and resize without resampling.
Note that the Resample option is NOT checked. And the pixel dimensions of the image (2738x1825x - seen at the top of the animation) do not change.
Same image, same quality, merely ...
Unsplash and Death to the Stock Photo are two favorites of mine. Great resources if you're trying to rid yourself of that typical stock photo look. More here.
Albumarium is another cool site for finding nice looking photos. Be aware that the licensing differs though, not all of them are free to use for commercial projects or without attribution.
There are several 100% free for commercial use options available on dafont:
Pixabay.com offers over 200.000 photos, cliparts and vector graphics, all of which published under Creative Commons CC0 as public domain. So the pictures may be used worldwide without giving credits and without asking for permission for any purpose and without limitation. I'm one of the founders of Pixabay.
The free watermarked, lo-res version of the image that jmort523 is referring to is also called a "comp image". E.g. on iStockPhoto, you can Download a comp as the link says under each photo.
The "comp" here refers to a comprehensive or comprehensive layout (see here). This is the initial layout mockup that you present to clients to give a rough idea of how ...
There are hundreds of stock photographs like these for sale all over the web, these being some of my personal favorites
If you just search for "device mockups" you should get a fair few results. There was a pack a while ago that was absolutely fantastic, that you only needed to drop your screenshot into a smart layer and it would adjust it to the device ...
Would you want to search for fonts where the rn & m are not easily distinguishable?
These metrics/facets are not defined in a font file or available in meta data. And can be Subjective. Making it difficult to create clear search facets.
Text or bitmap search can auto categorise and make safe assumptions about their content. There is a lot of value and ...
Wow, that's an exacting set of requirements. And you want this for free!?
But EB Garamond 12 has all of what you want, but as alternates: it has lining figures available as an option and a single-story 'g' included as an alternate. You'd have to reprogram it in a font editor or use HTML code to make the alternate 'g' and lining figures the defaults.
There's the OpenRaster format (Wikipedia; extension .ora), a proposed open standard for exchange between image editing applications. It is intended to support layered images, comparable to Photoshop's PSD and GIMP's XCF.
Currently it's only used by open-source applications like GIMP.
You can buy vectors at best prices in stock images sites like Dreamstime not yet mentioned on answers above.
If you don't find the vector you need, you can ask someone to design them in the forums at the same price of an existing one.
They also have a completely free sectione of high resolution Royalty Free stock images completely for free here.
