Hello how are you? I'm currently a IJCSA member and I will be the person helping you find the best carpet cleaner you can. I have passed many certs from the International Janitorial Cleaning Services Assication and one thing I will say is anyone that has done training with them are the top most professial work and customer service. You want to go with a person that cares and understand the pros and cons of carpets and customers. Be sure to get someone that knows about chemical hazards and the safety for you and your family also  themselves. Have professials that know the importantance of every step and why they are instore. Here's a link where you can find what you need but remember IJCSA professials are the way you wanna go!!!
