Advice requested for a new site…

Hi,

Thanks for taking the time to read my request.

I want to move a website I have already in Joomla to WP.

The construction I want to have is:

– a main website where I offer some services (administration and websites installs, etc)

1 . some sub-sites/domains with sites examples with different themes and colors. Where people can have a look to a final designed website I offer to make.

2. kind of shop where customers will be able to buy services and website design services.

So my question …

Is it better to have a multisite construcion?

or

1 base site plus some sub-sites/domains?

Cheers,
