Hi everyone Already next week I may start canvassing local retailers in my town for commercial W/C jobs. As I am a beginner, I have only a foggy idea about how long would any high street shop, office, diner, pub or restaurant take me. Moreover, my speed will gradually build up, so I can't take it for a constant variable either. Could anyone recommend me some system of storefront pricing that is NOT based on time assessment? Rather some way of pricing based on square feet, square yards or square meters, the height of storefront, number of window panes etc? Or should I resign on seeking such sort of system, do few storefronts for free and measure the time needed with stop watch, and at the same time ask all retailers for revealing the prices my competitors charge them? Any advice will be most appreciated.
