Hi Irish Mower. Welcome to Lawnsite.
Too many variables out there to specifically answer your questions. What is your market like there? What type of customers will you be targeting? High end residentials, mow and blows, commercials?
There is a ton of information here at Lawnsite that can get you started in the right direction. Use the search feature at the top right hand corner and you can review thousands of posts where most topics have been discussed.
Remember: Keep in mind that when it comes to pricing and costs, every area is different. What someone charges in Florida, isn't necessarily the going rate say in New York.
