MultiSite with domain mapping and SSL. What kind of hosting do I need?

Hi,

I’m hoping to set up a multisite and some of the sub sites will have their own domain names and some will need SSL (I think!). I will be selling stuff. I will be selling blogs, and classified ads, and amazon stuff.

I’m at a total loss on how to setup SSL, how to select one that will work properly. I’m hearing wildcard ssl due to the multiple subdomains, but, if they are mapped to a specific domain name then that wildcard, will it work?

So, I don’t expect thousands of visitors per day, maybe hundreds might be optimistic for the first while.

Should I grab a reseller account?

I know my plans can’t be unique! So, what type of hosting plan would you buy?
