My son and I are starting a new lawn service business. We want to start small (part-time) and then grow into a larger business. However, we do not want to be a full fledge landscaping company. We would prefer to limit our service to mowing and edging. Any helpful hints for getting started would be appreciated. Should we buy a software package for billing, what the best mowers / weedeaters / etc., and finally, how do we develop our client base without going out into the market and lowering the price?
