New Site Automation with WHMCS

I was looking at the WHMCS integration on HostGator's reseller program and WPMUDev's plugin. I was wondering how feasible it would be to create a turn-key site which offers a standard personal configuration and a business configuration. From what I understand, WHMCS helps automate but what I can't seem to understand is how to meet the needs of an online store with a dedicated IP and SSL. Admittedly, I am not familiar, so maybe it's a quick process.

If not, would I need to do this manually, and if so, what sort of time would this take do you think? Really looking to make a turn-key site for small businesses and offering many themes/plugins for differentiation. and on that note, will this plugin allow users to choose plugins (functionality) their site will need?

Thanks for your time,
