Unless labor is extremely cheap where you live, it's going to cost more money than it's worth to have someone fix it. What I propose would be very inexpensive and has a good chance of fixing the problem, and you may come out having increased your skills and comfort with fixing things.

You need a screwdriver or allen wrench of whatever matches the screws/bolts holding your bed frame together, and you need a piece of beeswax (candlewax will do as well, but it's a little crumbly).

The squeak is coming from two parts rubbing against each other. You need to sit, bounce on, roll on, and push, and pull on your bed in various places to see what makes it squeak the most. That should help you track down where the squeak is coming from. Once you locate it, unscrew it so that you can separate the squeaking parts enough to rub some wax where they're making contact. Then screw back together. Test your bed again. It's not a guaranteed fix, but it's likely enough that it's worth the gamble. Good luck!
