Just a small suggestion from experience: many people tend to wait for a sale and often plan purchases around times like Black Friday or Christmas. Even though your pricing is already fair, a tiny discount can sometimes encourage people who are on the fence.
I could be wrong, and you may already be doing well without sales, but I believe even just a tiny discount can make a big difference. Almost every store and service has a sale, but I never seem to see one for windy. Either way, I really value your service and will be purchasing soon regardless to show my support. :)
