I am currently doing only residential properties between 2000 and 40000 square feet. I have the opportunity do snatch a large 8.5 acre (8.5 acres of grass) subcontracted account for year long weed control and fertilization. I am new in business and have been dragging the hose. This will not be possible for this job, and I must buy some equipment. I don't want to get screwed, and since I have never used a PG or Z-spray or anything else for large areas, I'm not sure how to bid this account. I know that my product costs for the year will be about $3000. With 33% markup, this makes my product costs $4200 for the year. What about the labor and the extra overhead? I think that I am going to quote $1800 an application for 6 applications, for a total of $10800 for the year. Does this seem reasonable?? Please help if anybody has ligit input. I have searched the site, so please don't tell me to do so. This guy wants numbers today. So, if anyone has any input, it would be much appreciated. thanks!
