I mainly do tree and shrub work(pruning and removals). I have to do a bid for a commerical property. The owner wants weed mat, multi-color stone and shrubs to be planted in a 130' by 4' bed behind a retaining wall. I need to plant 32 shrubs at 4 ft apart. The shrubs cost $28.99 at retail, except for 4 wichita blue junipers, which are $109.00 at retail. Weed mat is about $98.00 a roll, which I only need one roll. The stone is $25.00 a bucket, which covers 50sqft. I charge $110/hr for 2 guys for landscape rate. I am curious what your estimates would be and mark up on the plants and material and if you would guarantee anything.
