HELP! An Investor Left Me Hanging

[Fitzgerald Hall]

Hello everyone, 

I have a property out in Cedartown GA under contract, 50 miles from Atlanta. I went through with the contract under the impression that the older more experienced investor who went to view the property and get the contract signed by with me would guide me through the process. Unfortunately this guy has disappeared and refuses to answer any of my calls. I also lost a lot of marketing time due to the fact that he said he had a few buyers who would be interested and if all else fails he would buy it. 

Of course none of this actually happened. So now I am scrambling to find a cash buyer in a rural area that I am not familiar with before my contract runs out. 

Theres more to this story but ultimately I would like to ask the community; How would you find a cash buyer in a rural area that you are not familiar with? If you couldn't find a buyer how would you explain it to the seller? 

Any help would be greatly appreciated.
