What type of FluentCommunity Pro license did you buy?

So, I currently own a "Single Site Annual License" and was looking to upgrade to the "Single Site Lifetime License".

But then, I'm also thinking of "5 Sites Lifetime License" because I'm interested in offering FC community development services. Side note: I'm running a service business, and web design & development (Shopify & WordPress) is one of my services.

However, I think the right approach would be to go for "Single Site Lifetime License" for now — and purchase "5 Sites Lifetime License" only after I get my first client for this particular service.

So, for those who are like me, I'm curious to know how they approached this!
