To handyman, or act as my own GC, or spend for the GC?

[Aubrey Ford]

I purchased a "mostly" cosmetic fixer upper to live in for the next 12-18 months. The entire house needs a makeover and a few fixes.

I am not handy in the least, nor does my W2 job allow me the time to do the work myself.

Is it better to work via an app like thumbtack and work it bit by bit, vendor by vendor. OR get a GC to handle all the different trade folk? I like the idea of dealing with just one person and having them manage all the trades. But is the value there given I have 18 months to do all the work? Keep in mind I will be living here, so each room they work on I have to vacate during the work.
