Hey there. I have a lot of experience with JRPG style Pixel artistry, I have worked on a number of Games on a number of Engines, including;
Eclipse,
RPGMXP,
TMW.
I have Created my own games with Eclipse and RPGMXP, so will be able to help you further with game design principles etc if needed.
I will carry out the Project you have listed, and any extra work you need can be negotiated (IE AI Scripts, Map design etc.)
