Hi Tom,
M name is Alejandra, I'm from México City and I will be very glad to help you with your spanish and as you wrote, you can help me with my fluency and vocabulary as well. We can practice by zoom, meet, skype, any platform that suits you best. At this time, I think it's 9 in London and hoping you'll listen to my audio right away, "keep dreaming, Alejandra" (You may think lol). Let me know if you're interested, we can start tomorrow if you want to.
Take care and stay strong.
