Does anyone know of some good, trustworthy property managers in the Provo, UT area?

Also, I am looking for a realtor who is knowledgeable and trustworthy and can walk me through this process.  

finding trustworthy vendors 

You also need to show that you are trustworthy and will close (Cash is a must for most wholesalers).Everyone seemed to cover the main direct mail points.The other thing is it's possible your area is just too "hot."

Here's an example of what I'm worried about: I study my market and learn it inside and outI am very educated in my niche I have put together a reliable and trustworthy team I find a house for 15% below market value (for simplicity - the house is $85k, it is worth $100k), which gives me a significant advantage in that I can have a higher cash flow and be protected against small market fluctuations I put 20% down I start renting out the property with an excellent property manager managing it for me I'm making $500/month in pure cash flow after all fees, mortgage, taxes, etc.Two years later, the market starts to take a turn for the worst, and the house drops rapidly in value by 35%I try to sell the house before it drops too far, but no one wants to buy properties when they know prices will continue to drop Rent no longer covers the mortgage and fees due to the incredibly cheap housing market, therefore the house is foreclosed and my credit and reputation with many partners is destroyed This.

Other then calling and interviewing, what other things can be done to create a solid and trustworthy team in my out of state markets?

I'm not real sure how to move forward from here in finding a trustworthy private lender.
