W3C//DTD XHTML 1.0 Errors

I have attempted to fix some of these, but i’m no code person and have had to refresh to an earlier date to repair what I have done. Is there a service or a tech that would be willing to charge me something reasonable to rectify these issues? They don’t cause site problems that I can tell, but if something is broke it should be repaired.

Thank you
Chris
