I wouldn't do it. It takes 3-5 years for someone to get naturalized through marriage to a citizen. That means you're tied down to this woman for at least 3-5 years. What if you meet a great girl during this time and she doesn't buy your fake marriage fiasco?
For $30k, that's only $10k a year. You're better off finding a part time job that you can work on the side that will pay that much. At least that way you still have your freedom.
