Need a google map callout modification

I have a google map embedded on a webpage located here - [login to view URL] As you will see I have an orange marker in place, when clicked on the marker it shows a callout with content. I would like to have this callout have tabs like what is shown here: [login to view URL] Additionally I would like to have the styling for this callout and tab system shown here: shown in enclosed screenshot. What I wouldlike to have is a system based on the requirements. I would like to be able to add as many tabs as I need on the callout and I would like to list my own content, links, and media such as video. Additionall I will be changing the marker images so we would like to be able to switch this in and out failry easily as well. I would be great if you could please supply different variations of the callout with maybe 4 tabs on one, 2, on another 3 etc. That way, we can understand how the coding for it works in that we can continure ot make more of them. So 3-4 markers on the webpage with a variation of the callout for each one would be great. That's what we would like. I hope this makes sense. thanks
