I started will a heck of a lot less then that. Also, you are going to hear a lot of the so called pros tell you about marketing and you need to pay SEO
for your web site and this and that.
Your marketing budget should be x amount of dollars and so forth and so on. Don't listen to them, you know what you need to eat.
Bottom line, you go out you hand out biz cards and have a nice flyer printed up at Vistaprint also consider a yahoo listing I do a paid one for 9.95 a month and in one contract it paid off for years now.
Get bonded, most businesses will only want a bond. In all my years of doing this I have had one, only one customer ask me for my ins. Now if you plan to do sub work then you will need it, but why work for someone else anyway.
Good luck. Oh and if you think you will not have any bosses to deal with in this business, think again for each customer you have they will now be your new boss.
My wife and I met a guy in a shopping center a few days back trying to steal one of my customers away from me, so I walked up to him and introduced wife and myself to him, he was a young guy with his hair in a pony tail and tats on his arms and legs.
So I said what makes you want to be in the cleaning business and he told me he was tired of having a boss, my wife and I looked at each other and started to laugh, he had no clue why we were laughing and I told him good luck and we walked away to go pick up my check at the customer he was trying to steal away from me.
