Create 3-4 3d fantasy Landscapes, 4 dungeons, and 2 PVP areas - Mobile Game

I was doing these projects individually so I felt this time I would just group it all together possibly get a better result. Here goes what exactly I am looking for. I am creating a MMORPG and need some things created for it, I have assets from unity store I would like them to be used, also any other things you might come in contact with. THIS IS A MOBILE GAME each landscape can be no more than 200 x 200. You must be familiar with unity. This is the platform it is being built. What I want: I want 3-4 different landscapes to encompass a different world. I will attach a screen shot of current so that you may compare quality. I want them to not be just hills and mountains I want them to be usable and beneficial as a game. I need landscapes that spark the imagination. I need 2 PVP areas they will be capture the flag type scenarios. They need to be epic as well if you could through in buildings or places to hide this will be a plus. Please refer to things like wow in their pvp to understand what I would like. I also need 4 dungeons I have a dungeon pack so this becomes easier, I just need them to be similar but different. I don't mind if you also use free assets in the unity store as well or if you find online. I am not picky just in the fact I want it to be EPIC! The budget enclosed is the max budget so I am looking for the most amount for the least amount of cost. This shouldn't be as hard since I am providing you with assets. Your not having to design from scratch. I have a programmer who will do coding I just need everything to be made scenes so he can mesh together. Communication and deadlines are my most important things. I have great reviews you will be paid as long as the criteria is met.
