Most serious and best equipped kite school in Peru is Perukite (Jose Rosas) I believe they have operations both in Paracas as well as Mancora.
In Paracas you will find other schools too: www.anavegar.com
(Guillermo Ruiz) who also have very good instructors end equipment, or Jorge Ibañez (don`t have contact details) who might not have such a broad equipment inventory and I don´t know his instructors, but he might be able to offer a full package.
I believe Skipp has been trying to sell his operation in Mancora which might affect his commitment to satisfy his customers.
September/November is a full 3/2 wetsuit season in Paracas, in Mancora you will get by with a shorty.
Bus service along the peruvian coast is very good and reliable, but Peru is a large country, take long travelling hours into account.
