Hello there,
I can help you out in making this interactive map for your cannabis website. I've been developing and designing Web and Mobile Apps for years now so I can make this from scratch. In the past, I've actually created databases for companies, most of them were actually for E-commerce sites and Apps. In addition to that, I've also handled apps that requires GPS or location based tech. I can give you a walkthrough of how I work on these projects so you will have an idea as to how I can make things work out for you.
Just send me a message and we can talk more about the system and the design you want for the map.
Thanks and regards,
Chindee
