There are huge numbers of DIYers in my area. Some contact us looking for some help either in technical advice of to do portions of the project, while leaving other portions to tackle themselves. Have any of you served as a consultant? Different from charging for a design, I mean going to the site and providing technical assistance for an installation. (Hands-off technical assistance on hardscape stuff primarily) I proposed it to a customer recently, offering my services for $50/hr, 2hr minimum per visit.
