This is a very good career for anyone with ambition. You don't need any formal education or extensive training. You don't need a lot of money to start. All it takes is a business licence and an ad in the paper or even just on billboards at stores. Also you need a car. And away you go. You can choose who you work for and when you work. You can make a very good living do this. And if you get real busy you can hire people to work for you.(and with you) I would definitly do this over again given the chose.
I am self employed and have 2 people working with me. I would very highly recommend this career to some one that may have very little education. You can make a fair amount of money and be your own boss. You can pick who you want to clean for, do on your own schedule, enjoy it while cleaning (listen to music) or what ever you like. I like to dance while working. There is very little cost such as putting an ad in the paper and supplies. You can make a very good living doing this.
