The budget for this project can be estimated based on the scope of work and the average cost of herbicide treatment services. The project involves treating 7,649 acres, with an optional 1,651 acres, which is a significant area requiring a substantial amount of herbicides and labor. The average cost of herbicide treatment services can range from $100 to $500 per acre, depending on the type of herbicide, the method of application, and the location. Assuming an average cost of $250 per acre, the total cost for the project can be estimated as follows: 7,649 acres x $250 per acre = $1,912,250 Adding the optional 1,651 acres, the total cost can be estimated as follows: 1,651 acres x $250 per acre = $412,750 Total estimated cost: $1,912,250 + $412,750 = $2,325,000 Therefore, the budget for this project can be estimated to be between $1,500,000 and $2,500,000.
