Hi everyone! I would like to say in the beginning that I'm not a developer and I signed here in order to have some kind of consulting with the persons, who have an experience of site development. The main point: We would like to expand our service with creating Map Listing Tool (like here: https://rentberry.com/apartments/s/phoenix-az) As you've understood all properties must be listed on the map with the prices and filters. I'm curious about: Which development specialist do we need for creating such feature? How long does it take to create this map? Do you know companies/developers that can help with creating such search?
You guessed right that it's javascript. The front end can all be done using javascript and google maps API with calls to your server and database to get the info. I'd allow a couple of days to do it, but that's because I don't do maps all the time. An expert should be able to knock it out more quickly.
