My Plan: I want to specialize on Google Maps, to help local Businesses to reach top results. For example if you google "Dentist, City XYZ" or "Plumber, City XYZ" there are tons of local businesses, that are far away from beeing in the Top 3 Results in Google.
Google always shows, if you google for "Service in City XYZ", the Top 3 results from Google Maps.
I would contact the businesses, that are very far behind in the Maps results and tell them, how many potential is wasted etc. And offer a solution.
So how I would get the costumers? Of course I would create a professional agency homepage, and my plan to contact the costumers are 2 different ways: Since english is not my main language I would hire a professional Telemarketer, for something between 8-20$ per hour. For my part, I would cold E-Mail the potential customers with a professionally written sales mail.
Bevor starting this, I would create a big database of potential customers.
When I would have my first costumers I would resell professional Google Maps SEO from established Agencys, preferably with a monthly plan to have a recurring income.
My budget for this would be around 4000$.
I would be happy about any suggestions, maybe an owner of an agency also can give me a few suggestions.
