Just launched a new site, using freelance developers to build valid xhtml for clients mockup designs. Any developers needing work or anyone need their psd/jpg/png slicing, get in touch. Slice MySite - slice-mysite.com Send in your PSD, PNG or JPEG and get it sliced for next to nothing! We turn it into valid XHTMl and CSS, and even optimise it for search engines. $110 for one page sliced - cheapest you can get. I find it's worth doing even though I can build myself, because it's so cheap!
http://slice-mysite.com/questions.html ^ not valid typos (Exlorer) And there are a million other people doing the same thing. $110 isn't the lowest price, but I wouldn't justify it based on that type of quality.
Alot of people doing this for about $20, Slicing is seriously the easiest thing to do IMO, so is validating, but hey, different people are different....
The people doing it for $20 often have the lowest quality in coding and are the ones coming to the HTML/CSS forums begging for help on what they're being paid to do.
