I am looking to buy your service and have few questions first:
I see the difference between the two plans (Basic and Business), and I only need the basic for my 12 domains/sites.
I am only worry that the you have so many clients on that plan, that the quality may suffer. The price is ridiculously cheap and the whole world should be on your servers.

Would I get better quality to go with business plan? I don't really needed for the size or bells & whistles it's just been more expensive, my logic is that the servers are not so populated like the basic.
I am sorry if I am so direct, but I am having problem with my present host. Lots of downtime and email is not getting delivered. I am only using 7 Gigs of bandwidth and very little disk space.
I am good guy who just want a reliable, trouble free host and willing to pay for it.
Also, if I would go with one year payment would you migrate/transfer all my 12 sites and make them work? Free or?
Two have MySql (one each) and I am lost in that department.
TIA
