Thanks for the reply Matt!
I had no idea the dirt was worth that much. Now I understand why he was willing to do the deal. I am still going to jump at the opportunity, I have no use for the dirt and sure don't want to fart around trying to sell it on my own. Sounds like a mutually beneficial deal, which is great!
I have been to my local NRCS office and they were no help. The lady I talked to was very nice but told me she couldn't do much for me. She said they used to have people to design the project but they don't do that anymore. She said on a project this small they have the person doing it submit a design that someone reviews and either approves or denies. She didn't seem to think this project would be a problem but also said it was not her call to make. She gave me a soil map and a list of people who build ponds in the area which is where I got this companies name. She however could not comment on the quality of work from any of them. I called these guys first because they have a good reputation in general for their excavation work but no one I talked to knew anything about the quality of the ponds they had built.
Happy Turkey Day everyone!!
