CJIII, this post isn't a slam, it's just the truth.
You could probably get outfitted for $2k if you're just going to do this part time and the factors of time spent on site, quality of cut, power and durability of equipment aren't a factor to you.
What Bobby said about a solo operation running in the neighborhood of $20k is right on. But the sad fact is that you won't be able to get commercially outfitted fo $2k.
You may try looking for a local LCO that is willing to sell some of his equipment at a deal.
