You're not as far along as I had thought. Hmmm...well as other's have said you need more knowledge before diving totally in. Go to your local library and see if in the business section of books if they have one for starting a lawn business. Here they do, it was written in the 1960's but a lot of the business stuff will still apply. This will give you an idea of where to go. Next look on the web at the SBA (that's for small businesses) and go through the tutirails they have. As for charging it's up to you. Charge as much as the job is worth to you. In the begining you will be slow and hourly may work best for that but there is a big problem with that, down the road you will get faster so the more jobs you can do in an hour the better money for you so personally I'd say by the job. You really need the business classes. If you decide to go into something else someday you will be able to apply what you learned to any business. Working for someone else may not seem like what you want to do but it will give you some insight into how stuff is done. You can then use your free time to draw up a business plan, get some advertising together and so forth.
