Roger (search for " by Roger") on Ebay usually has some. You can contact him with an email address and he will sell one without having to bid on it. Very reasonable in cost. You could also use one of the white MHX blanks with pink wraps and such. Goduster on this board has pink reel seat hardware available. Drop him a PM.

You can also paint a blank pretty easily. I've turned several blanks pink with a rattle can with excellent results.
