It depends on how big your project is, if you have money to invest then you can outsource the development part from freelancing websites.If you think I am trusted enough, you can share idea with me and if it impress me , we can discuss further.
I know not too much about web dev but i can code so give me that. I think only 2 persons should be required in the beginning
I think the project would be great for one who develops the site, and one who manages the rest.
