Ok, after asking for several days to get someone to send me a maintenance estimating matrix, and getting a few (they were all pretty much worthless) I decided to make my own last night. It is pretty user friendly, and I laid it out in the way that would be most convenient for me. There is a sheet called Variables in which you can change you labor and material pricing, and then the rest of the calculations is done by formulas. You can change it to time duration, but I just priced things on unit cost and broke them down. Feel free to suggest new items. I plan on fully developing this over the summer, hope this helps some. (I took out my labor pricing so any local competition wont know my rates, but if you arent an idiot, you can figure out where to plug in your own numbers.) Thanks.
