Best digital marketing agency/company for a vending machine business?

I've been looking into hiring a digital marketing company for my vending machine business and wanted to get some opinions from other operators.

I'm specifically looking for a marketing agency that understands the vending business rather than a general agency that works with every type of small business.

The main things I'm looking for are more qualified vending machine location leads, vending machine placement opportunities, getting businesses interested in snack and drink vending machines, Google Ads, local SEO and Google Maps, website and landing page conversion and general digital marketing for a vending business.

I've spoken with a couple of general marketing companies, but I'm not convinced they understand vending machine location acquisition.

Getting website traffic is one thing, but I'm really looking for someone who understands how to generate actual vending locations.

Has anyone here used a digital marketing agency or marketing company specifically for their vending business?

I'd particularly like to hear from anyone who's used an agency for vending machine lead generation, location acquisition, Google Ads, SEO or getting new vending machine placements.

Who did you use and what was your experience?
