I have only done the smaller 1-10 yard mulch jobs and was wondering where you guys would be on a job of this size. I am bidding on mulching the parking lot islands for a large discount store. They have 8 years of added mulch so they want the old mulch removed and new mulch 4"-6" installed. The details are: the old mulch can be removed with a Bobcat ($200 hook up fee, $100 first hr. and $65/hr after that) and cleaned up by hand then loaded at each island into a dump (couple hundered $$$ for the dump) and then the old material can be dumped behind the store on thier property. New mulch will be delivered in bulk and portions dumped by each island then filled with the Bobcat. I will have a few guys ($10/hr each) spreading and finishing the mulch. Each time I end up figuring something up i have the feeling I adding something wrong. You guys have a ballpark on where you would be basically on the mulch and the time. thanks.
