Yeah, it seems as if taviana is exclusive to epoch. Even without any of the mods installed. The only map that seems to support the latest dayz mod build 1.8.5 is Chernarus.epoch is most popular. on your control panel should be an icon to reinstall and you can select which mod to install.
vilayer support is pretty ggood. one thing you will need to know is how to edit your files because their system is rather unique. Here is a video from them.
Thanks for your time man.No map is "exclusive" for any mod, they might need some tweaks to put the vehicles in the correct spots. Vilayer may not offer a pre-configured installation of a mod and map combination and you will have to use a VPS. all you do is install the map of choice and the mod of choice (dayz 1.8.5) and add the map into your server startup file. In this case you would also replace the chernarus lines with tavi in your mission.sqm addons arrays. And, Bobs your uncle, you are running dayz taviana. You have to ask all your players to have taviana installed .. but thats another thread ... nobody said running a Dayz server was going to be easy
You are paying a minimum of $21.60 for 30 slots, $36 for 50 slots.
A VPS is actually cheaper and you can run whatever you want. The $12 server will certainly work and if your server becomes popular and you need more, simply upgrade to the next one which is still cheaper than a standard game server. I realize I always seem like an advertisement for vilayer, but they have good support and the prices are very affordable.
