Little help here please

I'm going to try and do a bit of an experiment in making my music available for wider use. You can already download the songs on a pay what you want basis, but that's not what I'm thinking about.
My plan is to make all the original multitracks for those songs available.
I have three challenges to this though:

1) the sheer amount of time it's going to take me to upload 55Gb of 88.2 24bit files.

2) Choosing where it should be uploaded to. I'm thinking a torrent site but with the pirate bay now being blocked in the UK (and not being particularly techy and not knowing how to get around that)  the obvious target has gone.

3) Getting word out that it's there. Back to the old obscurity problem.

Now obviously no-one can help me on the first one, but any advice or suggestions on the second two would be greatly welcomed.

Thanks
