In spite of some sound advice spanning hundreds of years of experience, let me ask you some questions.
How is your credit, is it bad, fair, good, great, or I have no idea?
Are you presently able to pay all of your own expenses every month?
Do you presently have any insurance for your lawn care service already in operation?
Are you in good health, do you presently have health insurance with your full time job?
Do you have any idea or plans on how to keep your contract if you become injured or sick?
Please think carefully before you answer all of these questions.
