Need Phase 2 Help in NJ

[Amit Patel]

We are buying a plot of land where we are planning to build some retail space (in talks with a national franchise already that likes location).

We did the Phase 1, which found nothing. However, being that we are next to a gas station, they recommend Phase 2 testing to be sure. The quote is coming out to 8K for testing. I thought this way high and was going to see if I can get feedback from other members on companies they used that were reasonable so I can get a few more quotes. Also, is it ok to let a different company do the Phase 2 ? Please Help as this is very new for me ( I own a few multi-families and have done all the oil tank,etc. stuff but this is very new for me).

I am not looking to quibble over a few hundred dollars but in working with multi-family contractors, I've had quote difference of several thousand and have saved a lot of money shopping around.  If you think this is reasonable and just go with this quote, I'd like your opinion as well. Again, very new at this Phase 2 stuff and hoping to get help from you experience Bigger Pocket folks. 

****Thanks in Advance for all your help. I have benefited so much from the Bigger Pockets Community.
