Why am I having trouble hiring a contractor?

[Caleb Palladino]

I have been trying to get a contractor to give me an estimate on an investment property that I have lined up. However I've had 3 contractors that said they are willing to walk the property and that they would call me back later that day to let me know of their availability. They never do. I leave messages and send emails to other contractors who don't answer the phone right away and none of them respond. I've even used Home Advisor to advertise my project but I'm getting nothing. I would like to get 3 separate bids to negotiate pricing but I cant even get one. What am I doing wrong? and how can I get better success with contractors?
