Hi,
I'm an experienced web developer, and worked on a few online games so far. Your changes seem minor, the kind of work that can be done within a day. From what I understand, you just need some new parameters set into the admin panel, so that you can set them to the desired values, and the teleport ability, which should be done fairly easy, just needing to change the planet's coordinated withing the world.
Please let me know if you're interested in my proposal.
Thank you and happy holidays,
Bogdan Panait
