The banker is free and gives you money. OK. He lends you money. You probably get a line of credit. Which costs a little bit when you use it.
The accountant costs some money. Not much, though. You'll make it back by the end of the year in tax savings, in money saved by efficiently using your line of credit, and probably money gained by a couple receivables you lost track of. This is all on top of the pleasure of knowing that your taxes are all correct.
The lawyer costs a little money. You'll make that back too. Your contacts, being well written, will not only protect you and help ensure you get paid, but will generate more money because you have broken out the right things as add ons, and you have protected your other opportunities for revenue. This is on top of the pleasure of knowing that your contracts are secure and do in fact protect you.
If you business makes enough money to pay you, your team will make money for you. Interview them and get them on board early.
If you haven't seen it, you need to watch a video. Search for '**** you pay me' where **** is a four letter word starting with f that means to copulate.
