Looking for someone to do a Shiny touch-trade with

Hey! I'm looking to evolve my shiny Swirlix and don't want to bet on the chance some random person in link trade gives it back rather than keeping it. Is there anyone who could help me out? And I'd feel the safest if it's someone who also wants to evolve a shiny, so that it's like were keeping each other's shiny 'hostage' if you know what I mean. Cuz I got only one more Swirlix evolve item and the shiny was already a pain in the ass to get :) So I really want the highest chance of actually getting my shiny mon back.
