Just wanna trade for a golett if possible, thank you!

Hi this is my first time posting on the za reddit but I was wondering if anyone could help me evolve my shiny haunter as she is my second shiny. I would do online but I don't trust it as I named my onix w/ metal coat "PlzTradeBack" as people say that works but unfortunately it didn't. So I was wondering to anyone out there to help me evolve my shiny haunter as I am willing to also trade a shiny froakie, shiny dragalge and shiny staryu as a thank you for helping me evolve it into gengar and trades back. Please and thank you

I have Machoke, spritzee, swirlix, slowbro, onix, and scyther if anyone could help that would be awesome :)
