Thank you for any input, feedback, critique.

 I’d like to start working for myself in the near future. I’m currently in a sales role doing well but have hit a market-wide pay ceiling. I’ve always wanted to start my own business but seeing the numbers i’ve produced for someone else is making me physically sick…that brings me to my question. Where to start? 
My father (no contact) owns an asphalt maintenance business so I was raised in the field but the physical toll is not one i’m really not sure i’m willing to pay and it’s hard to retain good employees as they tend to become your competitors as soon as they learn enough to do so, however I consider this the safe option as I can leverage my skills, mostly sales, and my knowledge of some of the ins and outs of the trade. 
 I’d really like to do almost anything else instead, the problem is that I could see myself enjoying so many things it’s really hard to narrow anything down. Like everyone else i’m looking for something i’d enjoy doing but honestly I care more about providing for myself in the short-term as I plan to retire in the next 12-15 years.

I’m looking for: something that clears 30k profit the first year something with starting cost under 50k cannot require the storage of large materials cannot be landscaping, I live in the desert

Bonus Points if you can find something mostly remote but that does seem a little to good to be true.

If you don’t have any suggestions for which direction to take, i’d appreciate a book or podcast that you feel is worth my time.
