Installation Questions - Still learning the costs

[Jeremy H.]

I'm in the Louisiana area and have a handyman completing a lot of the repairs on a foreclosure I recently bought - this one will become my primary residence. I want to make sure I'm not getting taken advantage of on the pricing since I'm new to the rehab part. 

I had him swap the electrical box and meter box - swapped from 100amp to 200amp from the weather head down to the meter box - charged me $2250 (Got quoted $3500 from my electrician). New larger electrical box, new meter box etc. 

Had him replace 2 doors today - went from wooden doors to metal doors. Included demo and buying and installing 2 pre-hung metal doors - one with a half window and one just plain white (included door, framing, bottom threshold, hinges, basic knobs and locks). I think these doors cost $300 or so for the one with the window and $200 or so for the plain white one. He's charging me $1400 - seems a bit high (but unsure). This did include the handles and locks - regular lock and deadbolt. He sent me pictures too, they seem to be installed well from the questions I asked (are the tight? any daylight?). One of them has a small dent in the bottom left corner. 

Have a quote from him for $5500 to tile 2 bathrooms. He'd have to demo the sheetrock, put up water proof cement board, and install about 140 sqft of 12x24 tile and frame out 2 stainless steel wall niches. I purchased the tile and wall niches so this would just include labor. This seems high to me and the research I've done. 

The guy does quality work and has a lot of experience and can literally "do it all". Just want to make sure I'm not getting taken advantage of here being new and all. What do you all think - do these costs seem ballpark? (Yes, I have read that popular book on the cost to rehab houses lol)
