Genfanad (http://genfanad.com/) is an browser-based MMO that's currently in alpha testing. We're looking for someone who's able to quickly use our tools to create Runescape-style maps.
We have a current map designer and we are looking to expand our team.
The world is tile-based, and primarily includes making a height map, importing models from tile sets, placing buildings and fences in interesting configurations, and placing scenery on tiles.
The toolset is open source and can be installed at https://github.com/Heleor/genfanad-level-tools -- read the extensive documentation and screenshots to see how it works.
We are open to hiring someone hourly or commission based. Our budget is about $100/map, but flexible depending on skill level.
