Depends on how much design you would like. I would look up the materials you would need/ desire, add it all together, plan it out (For designing and spacial moving for swimming/all other home materials), then actually make it happen it will take a while i believe you may do it.
Mermaids are priceless.

over $100.00 if you want a good one

Three whole pennys.
go to ebay

I lived in Oklahoma and at the Walmart, my dad found a fiddler crab for $3! Make sure their habitat is heated 75- 85 degrees
It depends on how fancy you want your costume. It could run from fifteen to two hundred dollars or more.
$0.00 because it's a horrible idea.
Well, you could make one yourself, but it would only be a costume. There is a video on youtube of how to make a mermaid tail. It is by Sasha and it is at http://www.youtube.com/watch?v=xtwnOQg_KH8&feature=related. That might help. If you are talking about becoming a mermaid and getting a tail that way, it can't happen. As much as you might want it to happen, and as much as you might believe it can happen, it won't.
You make it's habitat as much the same as in the wild
