I find a few usability problems with your site

- At the default size I find most of the text too small and pale to
read
- Text that is underlined appears to be a hyperlink but is not and vice
versa.
- Graphical text cannot be resized (some of the text is miniscule so
this is bad)
- Headings are too pale possibly because my Mac's gamma differs from
that of most PCs, non the less if the headings aren't active they
should be a duller colour.
- It is unclear what 'save big 50% and leave your mark on the industry
means', you should consider promoting the 'order logo design
immediately' feature which is much more useful.

This site does look clean and professional however I believe your
design focusses too heavily on presenting a slick style and does not
address the goals of your target audience. Having said that I do not
know what your target audience is-what is your target audience?

Is there a particular aspect of the design you'd like more detailed
feedback on?
