Thank you all for the response thus far. I have visited my local JDL, for a help with the starter program as suggested. I will start with it, and tweak it accordingly.
As far as the grasses we deal with here, we mainly deal with St. Augisitine, Bermuda, Zoysia, and Centipede. What products do y'all recommend? Can I expect good quality results from the product JDL suggest i.e. Pre-M 0-0-8 etc.
As taxes go, I charge tax on all the services we perform, so to be honest I am not sure of a right answer on that one.
Thank y'all again, and other tips or suggestion would be greatly appreciated!
