I have a customer with a 15x15 bed in the middle of a concrete parking lot with a tree in it. It currently has LS fabric and lava rock (approx 1" thick). He wants it spruced up so I figure I would remove the fabric and rock, till the & ammend the soil then install periwinkle. How would u break down his charges? Here is my idea: I figured it to be about 2.5 sq/yds: Flower bed prep, remove rock and fabric: $150 Disposal of rock/fabric: $60 2.5yd of landscape soil: $160 & Periwinkles 50 @$95 no mulch. DELIV Charge: $60. TOTAL: $525 Any suggestions? Mike Forgive me, because I mainly do tractor mowing and am working these small jobs.
