I require the same assistance. I have also set up a self-hosted WordPress site and installed Jetpack. My wordpress.com blog is at callyjackson.wordpress.com and my self-hosted site is at callyjackson.com. If you could please move my followers over, that would be great.
Provided you have installed and activated the JetPack plugin http://jetpack.me on your WordPress.org install, and provided the relevant URL(s) are posted here, Staff will do the transfer of subscribers and stats for you. I tagged this thread for their attention.
