Finding new contractors in new investing location-Philadelphia

[Michael Davis]

I've taken a leap of faith and am going to be investing into an area that I have never invested in before. I have a property under contract in the City of Philadelphia in the Francisville community. Property has lots of potential and will turn a great profit. However, my only concern is finding a reliable contractor in such a large city setting such as Philly.

What is the best way to go about finding a dependable, trustworthy contractor in such a large city? I have used apps like Thumbtack before that have been hit or miss (about 50/50) but would rather not leave such a large project in the hands of something that "may" work out. I have someone that will be able to perform some of the finishing carpentry work that I have used several times in the past, but do not have any solid connections with other trades...yet. 

Any input is greatly appreciated! Thanks!

Mike
