Hopefully you'll get some responses from agents in your area. I would also ask around to your friends, family and coworkers for names of agents they'd recommend. If you need to move in 30-60 days, then you need to start the preapproval process ASAP. (you can find lenders here, or ask around, or your Realtor could recommend one).
Once you know what you qualify for, then it's time to start house hunting! Depending on available inventory in your area it could take as little as a week, or several months to find something. Then the loan approval process can take 30-45 days, depending on the loan program you choose.
