yep, it's hard to give good advice here cause there is none.. the last shop I worked at before i started my own shop was spending $1,000.00 a month on estimating systems.. lol.... but check out compest.com not a very expensive system.. it's like 180 a month.... if you email me a list of everything your looking to do i could figure out a estimate of what i'd suggest,, but i'd need some pics also
