I'd develop my article website with a good coder and graphics designer, hold a contest on my message board paying people for articles that get used, then invest the leftovers into advertising.
I'd probably hire a gang of people somewhere cheap to do some extreme link building for several of my existing sites, spend some on PPC ads and maybe an article writer. Hmm sounds like I need a lot more than 10k
I'd hire professional article writers / web designers and have them submitted to the major article directories and then I'd hold forum posting contests with prize money to reward visitors for posting and turning into repeat visitors.
I like your idea actually. I'm surprised someone hasn't made something like that yet. And yeah, I bet you could do 2 girls at the same time with 10k. ;P Ah, how I love 'movie' lines. I'm not sure what I'd do with 10k but you all seem to have good ideas. I'm taking notes!
