Hey! I can help! I am trying to evolve my shiny porygon (two of them) too, and I haven't found anyone to help me quite yet. I'm free anytime in the hour after 4:00 PM UTC (12:00 PM EST) and pretty much anytime in the two hours after 11:00 PM UTC (7:00 PM EST). Just let me know if you're free at either of those times today!
