And this 3k includes actual permits and insurance and so forth? Yeah,
it may work, having a seat-of-the-pants repair job, done off the
books. But the downside is that if they eff up, and the house
collapses, insurance company may just look at your son and giggle.

That was my first thought, what ironclad guarantee is in place if the job
fails with resulting damage to the house? I'd want to know that if part of
my house fell down I wasn't going to have to chase this guy with or without
a gun.

References would be nice, talk to some previous customers and see if they
now have a swimming pool where their house used to be.

That price seems amazingly low, we spent more than that getting half a dozen
yards of sewer line replaced recently, I'd be real cautious.
