Looking for a Contractor

[Jaime Appel]

Hi All, 

I purchased a condo in Hillcrest area of San Diego that I'm using as my primary residence for now. I hired a 'contractor' to remodel my master bathroom and closet, as well as demo and level the concrete subfloor in my kitchen for to prep for DIY SPC flooring install. I did not do my research on him and find myself with a demo'd kitchen and bathroom and no contractor, as well as -$3,500 that I stupidly gave him as a deposit. I got a couple of bids before hiring him that ranged from $7,000-$25,000 which all seem expensive since it doesn't seem like that complex of a job, but I'm originally from a much less expensive area so perhaps I'm just underestimating the costs of work like this in SoCal. Part of me also thinks I'm being preyed upon to some extent because I'm a woman and they think I won't know any better, but maybe that's irrational. There are a ton of unlicensed contractors around here which I don't mind if they are capable, but I don't want to repeat my current mistake and shell out more money for nothing to be done.

I'm hoping to get some advice on the following:

1. What is a reasonable price for this?
2. Can anyone recommend a contractor in this area? Should I avoid the unlicensed ones? 

The job includes the following: 
It's an 8x6' bathroom. The closet is standard depth and 5' wide. The first guy demo'd it so that we could move it out into the bedroom by a foot and make more room in the bathroom. It's currently drywalled except the demo'd areas of wall and ceiling and the previous tub is removed. 

1. framing and drywalling the closet and part of the ceiling
2. installing a bathtub and either tile installation or prepping the walls for tile and I would DIY the tile itself
3. tiling the floor
4. install toilet and vanity
5. prepping the kitchen floor for flooring install (will likely need to grind the concrete patches the old contractor shoddily performed +/- self-leveling concrete)

Apologies for the long-winded post and I appreciate any advice!
