I am searching for an element which could create custom marker.

I attempted multiple Google Map Components. The very best one which I discovered was GoogleMap. It could appear just a little complex for any Map component, but after 2 minutes having fun with it you're going to get a practice it. Very Effective!

Or consider Googlemaps Plugin, it's very popular and it is a part of Joomla Code.

Phoca Maps should have the desired effect.
