I am sure there will be enough dwarf popuation to support a dwarf guild, if it is handled correctly. You have an interesting story to start on and I see nothing wrong with taking it one step at a time. However, I do think you could edit your first post to contain all the information and not scatter it around the topic, that would make it much easier to see what you are about.
I wish you the best and hope to see you ingame often.
