Just saw your post Ksss after I put my post on.
Thanks for all of the information. I have the desire to do it, and I won't be starting until next spring or summer so it gives me time to save money so I can get started. I looked around town and I am the only person that would be doing something like this, and that would probably change in the future.
I'll been working at are local green houses, and they have a backhoe that I can use, or an old backhoe attachment that I hope to buy from them. Thanks again.
