Vending location

I am in the Columbus OH area and have 6 machines sitting in storage. I work a full time job, but I am having trouble finding locations with the limited time I have. I cold call on my lunch break, cold call in the evenings but I feel like I’m getting nowhere with this. I’ve tried vending exchange, vending village and paid people on fiverr to try and find locations and I’m having no luck. Would anyone have any recommendations on what I can do next?
