How do i send a prepaid airwaybill in Lima ?!

[HoPe90]

Hey guys,

So I had to send my passport to Mexico for them to place my PR stamp in it, the embassy in Mexico is asking me for a prepaid airway bill and DHL said they don't give that, they contact the embassy for when the document is ready then go pick it up.

FedEx says they can give it to me but if I pay for it now then it means the document is ready for pick up and I can't say the document is ready for pick cause I don't know how long It takes to process it .

Does anyone have any suggestions?
