depends on how many other things you do besides lawn mowing. Obviously if you start with nothing, and what to do every under "landscaping" you are going to have put a lot of money back into the company, thus not making very much profit or any even. For me I did a lot of buying last year which was my first year and this year. Next year I won't need much, just the regular stuff any company will go through every year, like a case or two or three of 2 stroke mix. a spool or two or 3 of string for the trimmers and that's about it. depending on how much trimming your company does and how much 2 stroke gas you go through.
