In general, you're more likely to find a rooted plant this time of year than a cutting. Some one else here can probably recommend additional sellers that are close to you, but Florida Colors carries PP (although it's grafted, if that matters to you) - http://www.floridacolors.com/Penang-Peach-Grafted-Plumeria.html

Matt (1-stop-aloha) and Fuzzy (bloomingplumerias) on ebay are reputable sellers in Hawaii that sell PP as well.

kitnor don't know where you are in FL. but there is a grower here in Brevard who may have what you're looking for ...I've purchased several plants and cuttings from them - 100% happy. They have a FB page, B & B Exotics Plumeria ..perhaps they could help you.

http://www.a-piece-of-paradise.org Derrick of piece of paradise is very nice, and sells big beefy cuttings and rooted plants.

I've bought from Florida Colors, Sun Harbor nursery (not online), Maui Plumeria Gardens and Matt (1-stop-aloha). I've met the B&B Exotics guys and would buy from them. I would also buy from Brads Buds and Blooms, Jungle Jacks and BNJ Exotics.
