My advice is to use the P&P skills and equipment that you have for other people, companies and business opportunities. This "industry" is really a combination INSERT "red-headed step child" built off the backs of other industries due to a need.
For example: Many of these P&P companies require a PCR to be completed. They also do NOT compensate you for it. Solution, take the skills that you've developed and get the certification to become a home inspector. Pay is a hell of a lot better, risk is probably less, and the work is comparable.
Another example: If you have the equipment, skills and desire to turn a jungle into a manicured lawn, promote that. Talk to your city alderman. Check with neighboring towns. Point out that many of these shacks aren't being maintained, the city should be issuing violations and YOU possess the tools, and know how to fix it. You bill the city, the city places the bill on the property taxes.
There is nothing wrong with enjoying this type of work. There is something wrong when anyone does it only because they "enjoy it" or "prefer to be self employed". This is a business. Treat it as such. Pay yourself. Make sure there is profit for your company. Most nationals and all regionals just churn through contractors until the next guy comes along. They don't care if you make money or not. They only care that they make money. PERIOD.
Look out for number 1. All lot of us "seasoned old guys" like what we do. I personally have no hard feelings toward any Newbies. Just make sure you ask the right questions and you will get the help you're looking for. By the way, the wrong question is "Who is the best company to work for". It is the dumbest question that I see asked over and over again. There is no answer to it, other than maybe "Your own company". Everyone has different experiences, company overheads, PITA tolerances, vendor liaisons, etc.
Also, it doesn't hurt to listen to and implement the advice that you receive as well.
The best advice I ever received came from Wannabe. It went something like, "Stop walking past dollars laying on the ground while stopping to pick up a penny doing P&P."
