On the flipside, I gravitate towards services that don't require much support (I have never actually needed support from Amazon AWS, and the only time I talked to 1&1 was when there was a hardware failure, and really only notifying them was my entire involvement). If you are going to have support, for the love of God charge for it: 99% of people using cloud services don't really know what they are doing, are going to want a ton of support and are probably going to insist on trying your platform for free. Companies that know what they are doing know that that has to be paid for somehow, and it is coming out of their margins, which sucks.
