Scope of work question for flippers

[James Fitzpatrick]

So Im just starting out flipping, got my first house under contract (short sale) and im in process of finding a contractor. Looking for a GC, not looking to sub everything out myself. House needs basement finsihed, 2 bathrooms and kitchen fully renovated and master bedroom needs new floors and install a bathroom. Ive had 2 contractors come out and look at it but one wanted to charge me $500 for written scope of work and estimate while the other asked me to provide the SOW... My question is how does everyone put together their SOW? Im not a contractor so I dont know every line item that needs to be done.... Also I want a full SOW/line item quote so I can compare "apples to apples" when getting multiple bids. Any input would be greatly appreciated. Thanks.
