I have a few very well know industry accounts that will only pay for one time cleanups. once every quarter they call me and I go in and bid 3 times higher than if it would have been done every week. You just can't get it through their heads. 99 a month or 500 a quarter. You go figure. 1200 or 2000. fills the pocket though. Weed barrier is worthless. most bark breaks down and weeds grow ontop of the barrier any ways. Why waste your time and their money, just to look like a jack ass any ways. pre and post emergents are the key.
