Part Time Jobs easy on knee's?

I tore my ACL a few weeks ago right before I got out for school. I'm having surgery tomorrow and then have to spend a lot of time rehabbing and everything. I'm 19 and need a part time job but won't be able to do anything where you spend a lot of time on your feet walking around so something like a waiter is out of the question. What jobs are out there that would be good for me to do
