hi Mcnaz and welcome to the forum ! we are always really happy to hear about new epub creation tools being developped since at the moment we are still waiting for the "perfect" tool, and since different users have different needs.
please do keep us informed of your progress ; you'll find plenty of people around here interested in trying it out and giving suggestions, if you are looking for that.
and don't hesitate to take a look around the epub forum to see what else is available, and get some useful information.
