Dealership photography help.

Hi there! Sometime in the future, I want to pick up Car Dealership photography for extra money. But is it a good long-term career?

The listings I saw from Pro Motion Pics LLC say that they pay 24 an hour, for 5 days of the week from 8am-4:30pm. But Im worried about the limitations of work.

If I took this sort of job, would I be working for the company long term? Would it actually be for the full 5 days a week? What happens when the dealership is out of cars for me to photograph? Will I then be assigned by the larger company to go to a different dealership?

And then, what other jobs could I do to supplement this income if I don't get to work a full 40 hour work week from it.

And then what could I do after Dealership photography? Like realty photography, portrait photography, or tourist board photography.
