There's a company around here (I think it's a franchise) called "Let's Landscape (together)!" On their trucks they've got "together" in smaller text and in brackets. One of our maintenance customers went with them for a landscape project. They re-did her backyard for her. She said you can get 'em to do the whole job, or you can provide all the labour, or you can provide some of the labour (ie. landscape together). It's an interesting, if unusual idea. Personally, I can't see many of my customers being interested in humping wheelbarrows around all day under the hot sun, but hey - they seem to be doing all right so far.
BTW, she had them do the whole job. She scoffed at the idea of actually doing the physical work herself.
