Hi what you want sounds pretty simple to do and deliver back as a png. I've been using blender for years still not mastered it but I'm capable. I could do this if you would like or do any other blender type stuff. If you intend to supply the map texture it's something I could probably get done in an hour or two....render would probably be quick as you are working so low res..and I use gpu rendering. I did plan on making a remake of my old game flashback including the never made prequel using blender for characters and backgrounds...my ags knowledge has gone so I did some early art but shelved as project would have been to hard to do as I'd lost the original game codes...anyhow I digress if you'd like examples of 3d stuff I've done check here...
Just read someone's got it covered a few pages earlier. Best of luck
