Wow, first welcome to Lawnsite! It's going to be difficult for any of us to answer your question because it is rather vague. Lawns come in all sizes and shapes and customers may want different services. Also, unless we have a member on here from your neck of the woods, there is no way to know what the market will bear in your area.
Give us a little more info and we will try to help you.
Only you can figure out how much to charrge in order to cover exspenses & turn a profit. I won't drop the gate on my trailer fr less than $35-40. Depending how many lawns I have at that stop on my route. Posted via Mobile Device
The simple thing to remember is every dollar you make to put 25-30% back for taxes (closer to 30 actually), 20% for insurance, 20% for fuel, 20% for repairs and eventually new machines. I think there was an extra 5% for something else... anyway, even with 10 for your pocket, if a lawn costs 20 to do guess what, you have 2 dollars in your pocket free and clear. Doesn't sound like alot but guess what, it's the truth.
