Hi Blacksheep,
My only advice to you when you start this venture is Make a Plan, Plan the number of e-mails you are going to send, plan the number of companys you want to contact, Plan the exact date you wish to start the company, Set yourself a goal of whatever date in January that you are going to go for this and work towards it. As the saying goes Fail to Plan, Plan to Fail.
You have the cleaning experience, you know what chemicals and equipment is needed to get a great job done, once you start seriously planning this company things will start to happen and I have no doubt that you will get the work. One thing you will need is the support of your family, do whatever you need to do to get your hubby on your side and supporting you, its not going to be easy at the start so you will need his support and encourragement and you will always find words of encouragement on this forum.
MAKE A PLAN, WRITE IT DOWN, SET YOURSELF GOALS.
Good Luck,
John
