Unfortunately for you, whether your intentions were good or not, BFL has priced their (currently non-existent) lower end units such that there is no need for people to throw in for a mini-rig. It would not make sense for someone to take on all the additional risk you're proposing vs directly buying a Little Single themselves. You don't even have a place in line. Sorry if that shattered your dreams. 
+1Hey, at least you might be able to sell your domain name! Let's do some calculations:
1 share = $450
Mini Rig = 1,500 GH/s
1 share = 15 GH/s
Little single SC = $649
Little single SC = 30 GH/s
There's the electricity costs, but don't forget that you won't be able to sell your "share", and it only lasts for 2 years.
