Are you referring to SocialGo's $550 plan? ( https://www.socialgo.com/design-and-build )
You would need the UltimateWB Full software which is $249, one-time fee which includes 1 year free of any software updates. You can choose to buy a yearly upgrade plan after that or not.
You can use your own domain name as you said you can point it to nameservers for web hosting.
For web hosting you can choose an UltimateWB plan at https://www.ultimatewb.com/domain-names-web-hosting and that includes free installation of your purchased software onto your web hosting. (Alternatively, you could choose web hosting from another company that satisfies the server requirements as listed at https://www.ultimatewb.com/server-requirements . We have install instructions/video at https://www.ultimatewb.com/installation and optionally also a install service available for purchase at https://www.ultimatewb.com/pro-services ).

Now for web design packages, we have the Small package for 5 pages setup for $375 and the Medium for 10 pages setup for $750. We could do 7 pages for $525 if you would like. Regarding which pages you would like us to do, you can get some good ideas from the web design package info page at https://www.ultimatewb.com/web-design-packages-info . For example:
2) Contact page (footer link)
3) About page (footer link)
4) Terms (footer link)
5) Privacy (footer link)

Regarding turnaround time after you purchase, once we get any of the necessary materials/info from you it is typically within 1-5 business days. You would need to purchase the software (and optionally web hosting for free software install service), besides the web design package you want.
