Your last paragraph is the route to take. As a few here have said, you need to find a good accountant (CPA) before you spend one dime. Write a business plan ( I hated that ). There are usually business nonprofit help groups out there of retired business men that can give you advice ( I can't remmember what they are called right now)... look for one of them.
The way you buy equipment is based on a lot of things, also do not forget you need operating capital. So... ask yourself...do you really have as much money as you think to lay down for equipment?
Find a good CPA, make a plan then stick to it
carefully. Also, one last thing every owner out here can tell you a story about that one company that promises to send you all that business and make you rich, if you just buy that machine or this machine. Don't believe them unless they are willing to give half of the cash up front on that big job... Of all the promises I got over thirty years... only one every put up the money. The rest... well,
they found some other sucker... Steve
