Replacement cartridge?

I have a Pro-ject Perspective TT, Grado PH-1 phono amp and Blue Point Special HO MC cart. Over the weekend my sons had friends over and damaged the cartridge. The stylus is about 90 degrees to the left of where it should be so I am assuming the cartridge is toast. The dealer I bought the TT from has sumiko, dennon and grado, but I want them or someone other than myself to install and adjust the cartridge. The grado amp can handle low outputs I think. I would appreciate any advise, I need to get back up and running ASAP.

Thanks in advance
