a while back i posted two pre built character models that could be used for any character all you would have to do is uv map them and rig them with what ever you want
and hey presto you would have the characters you require
let me guess you cant uv map right
all is not lost
check out bond1 uv mapping and bond1 character rigging tutorials
http://forum.thegamecreators.com/?m=forum_view&t=80347&b=24
we relealise that most users cant model but we always like to encourge the ones who are willing to learn that little bit
not one is going to make the models for you
but i have started you on your way now
if you are willing to learn a little bit by watching bond1 videos that are free on this forum
i am sure you will be able to make the characters you require
peace out
