i have a client who wants a forrest in his yard. he has upward of $6,000 to spend on trees. i found a large supply of 8-12 foot trees that are half price this week. 2 for $130. i figured i would quote him for 2 times the price. i can put down 30 trees for $3,900 and make $1,950. the supplier is going to deliver the trees to the work site. i will have a crew of 3 or 4 working. is this a good estimate or should i consider changing it around? our soil in the area is lots of clay. is there any tools to help me dig these holes more efficently? also, i've heard aout giving a warantee on these trees????? more info on that also. We are in a drought area and watering is restricted during summer months. customer is aware of this and still wants to plant. what should i do for the warantee?? i can't guarantee growth because of the restrictions put in place. during the planting process...should i apply fertilizer/soil in with the plant?? i know i'm going to stake around the tree...not a problem there... please help me with this bid.
