Hello!
My name is Reuben Moorhouse. I'm primarily a game developer but I also have some experience developing minecraft plugins (and ran a minecraft server for around 1.5 years). I'd be more than happy to help you with this task!
While I think I'd be able to complete this project quickly and efficiently, I have a few questions which would help me provide a more accurate estimation of the cost and time that this project would require. You say that you want someone to adapt a minecraft world for a theme? What kind of theme were you thinking of? Also how large is the world or area that you would like to be themed?
One more question I have is, what do you mean by "home system?". Are you referring to a plugin which allows you to set a home (using a command such as /sethome) and go to it at any time (with /home for example). If so, then this should be done easily! If not, please provide more information and I would love to tailor my quote to fit your needs :).
As I've mentioned I have a lot of experience with things like this in Minecraft. In fact, at the moment I am building a plugin for another client which adds educational elements into Minecraft maps so that she can run a summer course for students in Minecraft.
If you have any further questions about me, my experience, or would just like to discuss the project further, please get in contact with me, I'm happy to chat! I look forward to hearing from you,
Reuben Moorhouse.
