Yup!! Was just there last week myself. Going from Dumaguete, Just past the airport on the left hand side is a rock and stone place. They have all sizes...from teeny-tiny to boulder size pebbles.
We bought 2 bags of small stones to decorate the top of the cement patio stones...300php/ bag. When we were doing our walkway, we wanted a little larger, smoother stones and it was going to be costly, so our handy man said he could go to the river and get it himself for free and that we didn't need to pay him to get it. We paid him anyway, back-breaking work, but saved us a bundle and he made extra money to boot!!
Rather than a new thread, I thought I would resurrect this old one. In addition to the pebbles, does anyone know of a contractor who will lay pebble pavement using epoxy to keep the pebbles in place? Or a vendor who would sell such an epoxy product made specifically for paving? Looking first in the Dumaguete area for the paving epoxy and will look beyond to Cebu and Manila if I can't find it here.
