I work in a hospital in Dublin, Ireland and I am trying to design an Interactive Google Map for patients who want to visit the hospital

I have signed up for an API key…

I am just wondering what is the best steps to go about designing this map and would you have any map samples or code samples…

Basically I would want the map to load, and to have an extra button added to the already “Map”, “Satellite” and “Hybrid”, the extra button being my map called SJH.

I would need a search function and then on the left, names of locations that users can select, and when they select the location they want, the marker would appear on the map of where that place is located.

I also have images for each location..

Any help would be greatly appreciated..

please advice
