I need some advice from you spray pros. I own a lawn mowing company. We mow about 250 accounts a week. My customers keep asking me to spray, so finally I just got my license. I will be spraying 2 large condo assoc. for sure. One is 275,000sf and the other is 435,000sf. I'm sure I'll get most of my other clients once I let them know I'm spraying. My question is what size(gallons), what make or model would be a good starter sprayer. Price isn't really a factor. I know that I'll pay it off. I'm tired of fighting Chemlawn over application rates they are applying and so are my customers. Please take a few minutes to help me. I'm in Montana so no need to worry about competition.
