Add more options to services booking process

It would be nice if you could add the feature of step booking in the service section. Let me explain: I offer a service like TV mounting. I want users to be able to pick other options like 32 inches to 50 inches or 51 inches to 80 inches at different prices, and furthermore, they are able to choose whether the technician provides brackets or not and also specify what kind of wall the TV will be mounted on, of course at different prices. This feature is going to make this booking plugin the best on the market.
