Wanted 2x Secret Garden Party tickets will pay £75 ono each and can travel to collect. ?

I am hoping to get two Secret Garden Party Tickets, we can only be there for the weekend, willing to pay 75 each or near offer cash. I can travel a certain distance across London to pick these up too, and will pay cash. Oli ***SGP say you need to write just a one line letter giving permission for the new attendees to use the tickets in your place. You will have to include details - name address ref. number etc. along with the last 4 digits of thecard used to book the ticket (or could print or email the original receipt which has this info on)*** So I will need this too.
