As someone who would enjoy a good bitcoin website (especially since I find almost everything out there utter crap at the moment) please limit the ads on your site. I know you'll want to make revenue, but coinurl links are annoying. And I will close a site if half the page is advertisements.

Overall, I think it could be a good idea as a comprehensive bitcoin resource if done well. Good luck.

Oh, and as for your last question. Personally, I think it would be better to go it alone, or find someone willing to help with the site. There is no reason in my eyes for you to ask for money in order to create the site. Money should come from content, not people 'investing'. At least for a startup site.
