I am looking for a Realtor and mortgage loan officer to work with. Referrals?

I am looking for a Realtor and Mortgage loan officer who is very familiar with and approved by the county for FHA loans and DAP programs for Harris County in Houston, TX. Recently I went through a nightmare of both. I did research and found a list of approved loan officers. I am speaking to one and its been two weeks and she still doesn't have the information she needs? So I have decided to ask the community in addition to going through the list.
