Can someone help me evolve my alpha slowpoke?

I have an alpha slowpoke I want to evolve to slowking. I have popped in to the slowpoke trade code a couple times, but no one ever offers an alpha back, and I already lost my alpha alakazam this way. Can anyone help me to evolve? Additionally, I have a shiny haunter I'd love to evolve as well. I can help you evolve your rare pokemon too.
