[quote="Liga"]I can sincerely recommend Javier Herrera of www.andeanface.com or any of his guides.
Yep, definitely recommend Javier and one of his guides Felipe Jacome. I know Felipe well and we've done a few routes on Antisana and Cayambe. Javier and Felipe are the best, well educated and experienced. Javier has over 220 summits of cotopaxi before setting up www.andeanface.com. the last time I was talking to him, Felipe was in Bolivia finishing his UAIGM training, which he should have about now. Top notch guys if you're looking for guides that are accomplished and accommpanying.
