For web hosting, you can start with one of the lower packages if you want.  You can view the web hosting packages/costs and domain name costs (scroll down the page for domain names) at https://www.ultimatewb.com/domain-names-web-hosting (under the Purchase & Download tab on the top menu).  Do you have a domain name yet?  If you already have one, you most likely can just use that.

The web design packages which you were asking about include adding e-commerce items, as noted on the Web Design Packages page at https://www.ultimatewb.com/pro-services#webdesign .  You can use PayPal as the payment gateway system.  That way you would not need SSL to secure credit card info, but you could get SSL for securing other data on your website.  We offer SSL here: https://www.ultimatewb.com/domain-names-web-hosting#ssl .
