Who can I get in touch with to buy a foreclosure at a sheriff sale in NJ?

[Sam Faas]

I found a property on the sheriff's site that I think is a good opportunity at the right price.  I am wondering if there is someone I can pay to physically go to the auction to bid on my behalf.

Just FYI, I am aware of the risks of buying things in foreclosure.

Can anyone recommend anyone like this in NJ?  Thanks!
