Help! Need Gold Replating Advice

Hi everyone: In my ignorance I silver soldered on a gold plated ring,
with the outcome that the plating vanished leaving bare naked

So I need to replate this thing. Does anyone know of a service
company in Canada (which is where I am) that will do this quickly,
adequately and at reasonable cost?

Alternatively a company named “Medallion” in Chicago
(> offers what they call
a safe, non toxic plating system for $30. Does anyone have any
experience with this?

Any advice on how to replate the ring or who in Canada to send it to
will be gratefully received.

Cheers & thanks
