Seo Software Reviews

How I can verify the quality of architectural and coding of a web project?
I'm not a programmer and would like to outsource the creation a website. How I can verify that the source is in line with industry standards and best coding practices. Basically, How I can prove or validate that the work is of high quality (ie, scalability, Seo, Canadian independent database of architectural integrity, etc)? Is there software available for download or I have to hire someone to review the code? I've heard of a program called "police style" C # development. Is there one for php? It would be an adequate tool for my needs? Thanks
The W3C has available several validators that scans through source file (s) and confirm if there are errors, breaking the rules, etc. Check out this for your profit margin / HTML validator: http://validator.w3.org/ And then more validators: http://www.w3.org/QA/Tools/
