Lets take the first one: Winter. Setup and takedown are the only things that change in the cleaning process. That and you either have to have a warm place to store your equipment or have a heater in your truck (prefer a heated garage) I clean unless temps go to below zero or they close schools due to weather
Cheaper customers. What? YOU choose your customer base and then market to that type of customer.
Cheaper Clicks? Why pay to advertise? Drop me in ANY city in the country and I can drum up business right quick. People buy from people. Go to Realtors, carpet stores, anyone that can refer you business.
Home town! Great! then you know people there and (like I said) people buy from people, not ads.
Look at it this way.....Target your customer and go after them (you are in control) OR just put out ads and let the customers target you (they are in control) Its up to you.
