Surfing Mexico in august - beginner

Hi:
Any advice for a beginner going to Mexico? I'm a beginner, I did a surf camp last year in Portugal and been surfing a few days in Costa Rica. I will be in Mexico end of august, it appears that Puerto Escondido is great - except for beginners.
I find lots of references to Sayulita - anyone been there? Puerta Vallarta?
Also, Mazatlan - but I can't trust mexicosurfshop.com, too much about how great they are and how everyone else suck bad.
For Sayulita, from Mexico DF, which is the better connection: Guadalajara or Puerta Vallarta? Or some third destination?
Thanks
