I have the opportunity to bid on a job the consists of about 300 trees and shrubs and 30k in lawn. I have always focused on the landscape maintenance. I have dabbled with small construction jobs and usually ended up charging 2-3 times the cost of materials. My question is that with a job of this size if I priced it that way will I end way out of the ball park or even worse...sell myself short? The builder is going to supply and spread the loam. I would be responsible for rake and seed, supplying and planting the shrubs and suppling and spreading mulch. Any help would be greatly appreciated.
