Hi Bill,
goto :-
http://www.wfshome.com/ and download their program called
Fileshare pro ..
This enables you to give out your computer ip address and one port number which opens only after a given password is selected..create a web page that links to your site..then once theyve paid give them the password ..once the file has been downloaded remove their ability to access your machine..
ps no i dont have shares in it lol
hope this helps
