Is there a professional service or product anyone recommends for improving the ui of an existing asp.net web forms application?
All web controls/elements use css classes and there is a single css file where the look and feel and be controlled. I'd like to have a professional designer improve the color scheme/font/layout, without having access to the code.
I'm not sure how you would hire someone to improve the design of your site without giving them access to your code - unless you're willing & able to implement someone's design.
If it's just CSS changes, then you should be able to hire a good web designer from CraigsList to make the CSS changes "locally" and then provide you with a new CSS file that you could upload to your site.
Often times web designers will create a PhotoShop file and and hand it over to the developer for implementation.
I agree with Terrapin. However, If the site is already coded with a Skin, you could just give them the Skin file and let them toy with that.
