About myself: Working on getting CFI/II soon. With 500TT, 120+ Simulated Instr./Instr., 200+ Complex. Hold a full time job WFH but require working strict 9-5 schedule. Willing to relocate.
Question 1: Would like to know what are my options for finding evening/night/weekend opportunities in a 135 OP. I will be doing some CFI work but would also like to work in a 135 OP, if possible.
Question 2: Best locations for finding 135 opportunities.
Best regards and many thanks.

135 tends to be found around large concentrations of business activity and money, ie large metropolitan areas like SOCAL, NORCAL, Wash DC, NYC, Florida, Houston/Dallas, Chicago, etc.

There are night 135 opportunities, but they are often ALL night. You probably can't take a job at a larger 135 op because the junior pilots don't have any choice of schedule.

You will need to find a small 135 or 91 operator who will let you be flexible.

What would probably work best for you would be to market yourself as a contract pilot available to multiple operators. Small operators might use contractors when
1) One of their pilots is sick/vacation
2) They only employ one full-time pilot, and use contractors for the other seat
3) They don't employ a full-time pilot and only use contractors (rare)
4) They need an experienced babysitter while breaking in a new pilot

The problem with that is you need extensive experience in type and obiously a type rating. You would need to get 1000 hours, then get into a turbine plane, and then get 1000 turbine hours. At that point you could market yourself as a contractor (very much a who-you-know industry).

Thank you so much for a detailed and informative reply. This is exactly what I was looking for. I posted this on jetcareer's forum as well and together (advice from there and yours), I realize the avenue I will have to take. Again, I really appreciate your detailed reply.
Best Regards.
