For Shonkers Requests, I normally operate on a name-your-own-price policy. Assuming the item you want isn't expensive and/or difficult to obtain, you can pay whatever you want. The best way to tell me you want something is to list your request on the Shonkers wiki page, which I check frequently.
Shonkers HQ is located at 6b Cheesemongers' Yard. If you need help getting something from there, let me know, and I'll see what I can do.
I do not have arcane or mystical transport. If you are far away and in need of a badge, the best I can do is recruit you into the club and send a badge through the AM Post Office. If you are in a hurry, you can buy your badge for &&&&&&&&&&&&+400 with "replace insignia for QMA" at your nearest service area instead of waiting for it to arrive in the mail.
