Are they both going to replace (install) a metal drip edge, or will one of them just let the shingles hang out a little more and tell you it's no problem, it works the same?

Was hoping someone could provide some recommendations for how to go about doing the proper research outside of the US.

Installed two sets of double french doors where two outdated sliding doors were.

Then have them pay you that amount before you install it.

Enlarged bedroom #1, replaced all flooring, install new HVAC system (install central rather than use window units), replace dilapidated siding, install fencing and exterior curb appeal.

In Texas, like @Steve K. said, you are a customer without an agreement and you are a client with an agreement, meaning with an agreement they have "fiduciary" duties to you and you will be properly represented.  

I personally feel like carpenters are one of the most mysterious and aloof people out there...Anyways, I request a lot of bids for each part of the rehab process and along the way I've found some pretty great people that are cost competitive and provide high quality work.For example, I can provide some pretty solid recommendations for:Egress windows, electrician, window installation, storm doors, flooring (carpet/vinyl planks), hardwood floor refinishing.I can provide contacts for other jobs like carpentry, drywall, etc. but the ones listed above are the best of the best.I've found it pretty challenging to find a reliable handyman and carpenter.

They sell flooring there, but they also have installers.

One thing that has held me back is my fear of handing the financials properly. 

So it will require installing some wire from the load center (breaker box).If it's gas, then you just need a 120v circuit but will need gas piped to the location.The outlet for the washer needs to be GFCI.As the previous poster mentioned, the drain line could get a bit challenging as you'll need a 2" drain pipe plus venting for that pipe.
