Come up with a different strategy.
Many of those folks seeking a trainer aren't looking to throw up 8 reps of 225. They need someone to motivate them, do some moderate strength training and get their fitness level up. I'd look at offering a service to go to train them in their home. Slowly build up equipment you can take with you like a lightweight flat bench, adjustable dumbells, etc. My brother-in-law has a guy that comes to his house and jacks him up for an hour. I think he pays big money for it too.
