Hi Zach
And a belated welcome to the board and, hopefully, to our wonderful industry.
Your thoughts about starting a new business are correct. But also totally wrong! We will all have several ways of regarding and describing what we do and will not necessarily agree with one another. So I'll give you my perspective.
Cleaning carpets is not a hobby. It may be a passion but not a hobby. So it's a business. So it would be fair to say that we are business people and our trade/service is carpet cleaning. For myself, it's easy to prioritise my strengths and weaknesses. I'm a tradesman first and a businessman second. At the bottom of the list is salesman/marketeer. Luckily, I grew with the industry and have never really had to go out and sell myself.
As you are starting anew, it's my opinion that you should regard yourself as a businessman first and foremost. Apart from learning your new skills of trade, you'll have to go through all aspects of being in business. Things such as training, equipment, vehicle, insurances, office equipment, marketing, trading name, advertising, stationary, bank accounts, work wear, accountants, health and safety, maybe company name and logo whether to V.A.T. register etc. etc. As you can see, there are lots of things to occupy yourself with when becoming a businessman!
As for your last paragraph above, your customers are looking to buy a cleaner carpet, but if you're looking to provide a high quality service, you will be giving them more than that. You will start by not only arriving on the day as arranged, but also at the time agreed. After your customer recovers from that shock, they will be impressed by your attention to detail. The caring way you treat their treasured possessions, maybe cleaning some small mats without being asked and f.o.c. protecting the entrance and machine areas with protective mats, tabbing furniture legs, grooming the pile afterwards and so on. Your new customers will be so delighted with their new found "treasure" of a tradesman that they'll never want, or need, any other cleaner.
There are lots of one line snippets of advice that we can all give, so here's mine. From day one, start a database of customers. You then have something tangible as "goodwill" to sell when you retire
Safe and happy cleaning:)
