I've got it, follow these 2 simple steps:
1) Log into ebay. Say you are offering a date with a lady, highest bidder wins. The highest bidder must be able to get to Seoul on <insert winning date and time>. They must also supply a photo.
2) Email her saying... I have changed a lot in 4 years too, heres my photo <insert photo of winner> meet me in Seoul on <insert winning date and time>
