Somebody experienced to give productive criticism?

I'm hoping this isn't breaking rules in this particular forum but I don't have access to the MISC forum. Does anybody know of a user or a service that will look at your marketing website and give you some pointers? Home page, ease of navigation, article feedback, etc. I'm pretty new at this and though I think I'm doing alright, I like to have people with more experience give me some feedback. Thanks!
