Keep my wife in the USA!

Dace and I have been married for a year and a half. I am American, and she is from the Latvia, where we lived for a year right after our marriage. We are both artists and musicians with a dream to have our own creative school. Right now we need to establish ourselves in the USA, which means she needs a green card. This is a very expensive process; the first step is two government forms and lawyer fees that total near $2500, plus we need to get her a medical exam and other documents. I don't have a high paying job, and she cannot legally work, so we need your help! We need to pay these fees upfront, in a matter of weeks,  to begin the immigration process. If not, she will have to go back to Latvia at the end of July and we will have to be seperated for a time. Please help keep us together as husband and wife!
