I just found out I have to have a license to apply fertilizer. luckly I found out not the hard way but from this site. now I am in the process of getting my license and now I'm wonder after all the fees and ins. for a license how many accounts do I need to really break even? my main service is mowing so I already have two maybe three accounts wanting fertilize apply to there lawn but I want to not get in trouble applying it. so how many accounts would I need to pretty much break even from license fees to insurance ect? I know you can't tell me exactly since you don't know pricing here but for you what is ball park number accounts to break even? thanks for the input.
