Cartridge Alignment

To do it right, and there is probably no component that needs to be done right moreso than a tt/cart, I would suggest that you look into Boisclaire's website. Or give him a call. Tools there to help. Or you can call, very easy to talk to.

Should be easy. If you’re in for a long run, I highly recommend Dr. Feichert new protractor. It’s not exactly cheap but you will use it more than once and that’s for sure! Plus you will save on paying someone to set it up for you. It will pay for itself

I believe Michael Fremer has a cartridge set up video. If you can spin a screw driver and use a pair of tweezers you can do it. As long as the stylus guard is on the cartridge it is hard to hurt anything. Never overtighten anything. You just want snug. The money you would spend on a shop to set it up would be better off spent on a tracking force gauge and a protractor.

It's an Audio Technica LP-7 turntable. Sumiko Blue Point # 3 cartridge.

See if Audio Connection in Verona offers this service. Otherwise if you have a good protractor and a stylus force gauge it isn’t that difficult to do. 
Out of curiosity, what table and cartridge?
