Is the Sitepoint Forum an appropriate place to request a proposal for the visual design and development of a website near completion?
Not quite sure I understand your question, but if you're looking for people to work on your project, then no.
You can purchase a listing on the [SitePoint Marketplace in the [url=http://sitepointmarket.com/service-providers]Find people section](http://sitepointmarket.com/).
Does that answer the question?
It is actually free to list in the Marketplace - a fee only applies if you want to upgrade your listing.
