Hi Simon,
You can find some electronics stores that sell tvs and talk to them about your calibration services … but before anything about what you charge … tell them you will calibrate their tvs in the store for free so that they are always looking their best. The store need not pay for education or test equipment to get this done. In exchange, if they like your work, they will tell clients about this service. So as a store … they can offer clients THX Video Calibration services but through you. The decals are handy here as you label the TVs you work on in the store …
Then go to another store and do this again …
Hard to turn down a person when he is offering them something that is free to them and won’t cost them anything. Should be win win …
I also give some of my dealers a THX plaque to display in their store … it’s a $25 investment there.
regards
