This is the problem we've got to get over--feeling like what we're doing is not worth the pay.

I would say the definition of landscape designer and project manager are two separate items which could and probably should be addressed in concert with one another. Under landscape designer you may be responsible for initial contact(s), design, preliminary scheduling, budgeting, and bidding. The landscape design element easily bleeds into the project management side where you may be responsible for daily construction scheduling, quality control, contractor selection and qualifying, budgeting, and materials scheduling.

I would say, IMO, 5-15% is fair, varying by the complexity and involvement you may face in the project. It seems to me like this fee could be generalized as a "kickback" from the contractor for hiring them for the job. Each job would have a pre-determined PM fee regardless of the final contract with the installer. Some jobs may net you $50bucks, and some may be more "full-time" and on-going and net more like $2000.

One way you could look at this is to charge less for the upfront design with an agreement perhaps between yourself and the client to read something like,"Landscape and Construction contractors for this project to be selected by SAS Landscape..."

Just some thoughts..
