95 Accord transmission question

I have a 1995 Honda Accord LX with a standard transmission and about 220,000 miles. Recently the transmission has started getting difficult. It doesn’t like going into first or reverse as much as it used to. There’s nothing broken yet so far as I can tell but I think it’s beginning to wear out. I was tossing around the idea of getting the transmission rebuilt before something actually breaks but I wanted to get others suggestions and advice. I’m in college and I use the car for delivering pizzas part time. It’s a fun job but rough on the vehicle. Because of this I really can’t afford a new car but I do have some emergency funds set aside in case I need a major repair. I guess my main questions are:

Would rebuilding the transmission on an Accord with this many years/miles be worth it, or is it just a matter of time before something else expensive and mission critical breaks?

If I should do it, where would you recommend getting it rebuilt? Could my mechanic handle the job or should I go to a transmission specialist?

If I shouldn’t do it, what alternatives would you suggest?
