Congratulations on your success, I suppose minus the costs for an individual this would be a healthy income, it or depends on your driving vision for the site, if it is to maintain that traction then I must agree with other comments that doing this alone simply wont work. If youve got good numbers as youve showed theres every chance you can try for funding.

I must also note that while I am very glad you have succeded in your milestone and its obvious benefits from a marketing standpoint, I find the whole area of self promotion on such an early scale somewhat of a recipe of disaster. My own startup (Travel social networking / Commerce site) is in private until september time yet from friends, family and testers our turnover and profit in the last 4 weeks dwarfs this figure. I could easily push these figures for marketing purposes but until i have sustained traction in reaching our targets they add no real benefit to us.

Nonetheless good job, but go get some extra help with that money!!
