Don't go into business without the following-
1 Superior knowledge of the service you plan to sell. Work for another landscaper first, or go to school, or better yet-both.
2 A well thought out business plan. Already covered, press search.
3 The proper equipment. Beg or borrow, don't steal.
4 A back up plan AKA a way out if you fail.
5 Enough money in your savings account to break even or lose money for a while- just in case.
6 Most importantly-CUSTOMERS- Nothing will work without some of these. If you don't know where you are going to get them then you had better figure it out.
The day has 24 hours. If that's not enough use the night.
