I am experimenting on how to go about assessing what to charge somebody. I knwo what I want to earn with my wife or mysefl working (both degreed horticulturists). Has anyone given their equipment a set hourly rate $. For example, if I were to do a leaf cleanup with just me and a rake. It would take me say 8 hours. If I took my backpack blower along it might take me 6 hours. If I took my backpack blower and my billy goat walk behind blower it might take me 4 hours. If I want $35 per hour for my time. How much can I charge for each additional piece of equipment? If it saves me 4 hours out of the 8 can I charge $70 per hour for me and my blowers instead of just the $35. Basically I am wondering if because I was more efficient with my equipment how much of the saved 4 hours can I charge for. Need clarification let me know, if you understand what I am saying please reply.
