Just my opinion.....
Does my website have a professional, high-end feel? Why are why not?
No. Using 3 separate typefaces - sans serif, serif, and script confuses the message. This is compounded when you change fonts mid-sentence like you've done with the script in the page content. "Creative designer of upscale and high-end" is an incomplete sentence. Setting only that in the script makes little sense to me.
Consistency when choosing typefaces would offer more "high-end", "professional" appearances to me. Either use a serif or a sans serif. If you want to use a script, set an entire thought in the script. To me, the script you've chosen is also pretty low on the readability scale - even at the full image size.
Does my current "Call To Action" button stand out or can you find it easily without much thought?
Sort of.... Due to the lack of content, yes the single button is easily found. However, if the page had more content a purple button in the middle of a purple page will be lost.
When you have a dark page frame you subconsciously tell users that anything dark is part of the page chrome. Users will inherently tend to look over or not pay attention to those areas which match the page chrome (banner blindness to a degree). By creating a purple button you've hidden the CTA a bit. As posted, it does somewhat work as it currently is, but with 4 or 5 more paragraphs of text, a couple more images, etc. it'll be lost or at least much less prominent.
