How much would it cost to start a lawn care business with the insurance and all?

How much does it cost to start a lawn care and landscaping business dealing with: retaining walls, mulch beds, laying out landscape designs, lawn mowing, and constructions of decks and patios. And also what would be the grand total abouts with the insurance and all the equipment i would need? Thanks! :)

depends on what equipment if any you already have -
for doing the landscape design portion - it won't cost much -
at all
for the lawn care - if you want to start with good equipment -
you'll need at least one walk behind mower, and a good tight radius mower - figure about $6000 - $8000
a trailer - $2000 ?
Pickup truck - used/new???
tools - rakes, shovels, etc..... $300- $400
chain saw - $300
trimmers- $250 ea

for the deck building - unless you want to dig footings by hand
figure on either renting a power auger for each job - or buying one - if you buy probably around $1200

then saws, hammers (manual - pneumatic??) levels , compressor, generator- etc...
$300 - $4000 depending on how much you buy

and you better have some operating cash as well -
at least $2000-$3000

for your lawn cutting business - you should get paid weekly - or try to set up contracts where they give you a downpayment at the begining of the year - and then pay you monthly

on your landscaping business - they should pay you something for the design - if they give you the landscaping job tell them you'll deduct the design fee off the cost of the landscaping job - for the landscaping you should get
1/3 up front - 1/3 after all the beds are prepped/top soil in and shrubs delivered - and then 1/3 when you complete

same holds true for your deck jobs - 1/3 up front - 1/3 when materials get delivered - 1/3 when complete
