MIM Jazz setup

I just got my j bass a couple of days ago. I got a brown sunburst and I have already added a tortise pickguard. Even though I have played for several years I have only owned 3 basses so I am not that familar with action, string height and etc. I just play them the last one was a used bass that was set at the music store were I bought it. This new bass I mail ordered from MF. When the basses are shiped from the mex. Fender plant how well are they set up? I asume that answer will be that each is different. It plays good for me but like I said earlier I dont know that much on set up but I would like to have it set up as good as possible.

Also what would be an average rate for a music shop to check and adjust the string height.

Thanks

Steve
