Cheap 'Singapore weekend in BURSWOOD, Western Australia for sale

If anybody is interested in a quick weekend trip to Singapore I am selling a cheap ticket that my son is unable to use.
The jetstar flight leaves perth airport at 8.10am on Friday 11th October and arrives in singapore (changi airport) at 1.45pm
the return flight is also jetstar and leaves on Sunday the 13th october at 5.50pm and arrives back in perth at 11.10pm
there is a 20kg baggage allowance
the costs you will need to pay are for
1) the $40 fee for name change on the ticket
2) the difference in the price of the airfare when it was purchased (for $527) and the going rate when you change the name ( the current price is now selling for about $575) so if you were to register now for the ticket you would be liable for about $50 .
I would prefer payment via PayPal because this gives protections for buyers and sellers.
