You can send me your files via your favorite file-sending service, or you can use my ads-free registration-free YouSendIt dropbox for easy and hassle-free sending of files up to 2 GB
(when sending multiple files, like a song for mixing, please make a zip-file before sending)
Send your files to my YouSendIt dropbox 

FTP
I also offer personal ftp-accounts to all customers, just send me a note if you'd like one.

If you have any questions, feel free to contact me
