I need help finding a good general contractor in Philly or Jersey

[Jerome Johnson]

Hi, my name is Jerome, and I am new to real estate investing. I currently have a single family house I own that needs a total renovation. After using the bigger pockets rehab calculator, it determined I would need $90.000 for a complete rehab. Currently, the property is a single family I would like to turn into a duplex.  My question how do I start, since the property is in Philadelphia I have been told I will need to contact an architect before I can have a General Contractor begin the rehab. Is there anyone here know of how, and what I need to do? The property located in an up and coming South Philly neighborhood. Currently, finish houses in the area are selling for $200.000.
