I’m kinda surprised no one mentioned it yet, so please allow me to do it: you should learn how to do your own setups. It’s not hard, and it requires only a couple of very basic tools.
The thing is, no “expert” will be able to setup your bass just to your liking. Only you know what you like when it comes to string height. If you know how to do it yourself, you can always quickly adjust your action if it’s not exactly the way you want it.
Oh, and strings can make a huge difference to how your bass sounds as well, so you should definitely also learn how to change your strings. I don’t know what strings you have on your bass, but it might be as simple as changing to different strings to make you appreciate your bass again.
