Hi Sonya,
We all have to start somewhere & the best way of starting out would be to get yourself enrolled on a carpet & upholstery cleaning course, or possibly go to an open day and meet other carpet cleaners. The courses will teach you what you need to know about cleaning, spotting, different detergents, fibre identification, and the different types of machinery available. You will also find out if this is the type of work that you want to progress into. To clean carpets properly means buying the right equipment and these do not come cheap. You will find that the rug doctor and small karcher will not be man enough for the job. The other option for the time being would be to contract the work out to a professional carpet cleaner until you are ready.
Hope this helps
Derek Walker.
