Please log on to my website - http://www.sallyrosenman.com - and go to Referrals. Under mortgage brokers and bankers I have quite a few good people listed. I would call or email Robin Powell or Serena Greening as they are excellent.
Start with your own banker where you are, see if they have a relationship with a nationsl US bank. If you are a US citizen and pay taxes here that will document your income. Wahtever don't be discourged if it doesn't go well right now, the lenders are smarting from thier stupidity of the past few years.
Shoot me an email and I can give you three references for excellent finance people. I also work regularly with a title company who has handled overseas transactions.
