How much should I charge for holiday cupcakes & cookies?

I make holiday cupcakes & cookies that look like special characters or things. Like santa claus, reindeer, pumpkins, ghosts, turkeys, ducks, bunnies, etc. I recently made a golf course out of cupcakes. My family & friends think that I should begin to sell them throughout the holidays. I love making them & coming up with the designs. I just don’t know how much to charge for a dozen or where to start. Any suggestions or help?! Thank you 🙂
