I am looking for a site that provides services like Wilogo
but with more reasonable prices.
Do you know of any alternatives?
If it's so easy, just do it yourself. Make it in Microsoft Paint. It will cost nothing at all but your time.
Then you can save your money for the 3 $100 computers you are buying from Goodwill.
Even if someone is making minimum wage then $295 is like 30 hours of time. And you only make minimum wage if the requirement is "show up for work" and don't pick fights with the customers.
But here, if you want a cheaper logo, this is the guide for you:
Maybe your start up's bank account is running on empty.
But, don't expect to find much love for that approach here. You're addressing people who are (hopefully) charging $1000+ USD for decent branding work. A well-developed brand identity is going to start at $2500+ USD on the low end.
These sites have the low quality, low budget goods you're looking for. Good luck with that start up.
