I would propose the following:

Keep the current pricing for up to 3 teams, then add a nominal charge for each team over 3...like an additional $5 per team per month.

I would not really want any special rates for "Founders"...but would favor giving "Founders" a preferential draft pick in the rookie draft. (something like a lottery for founders only with the first picks in the rookie draft going to founders, then have the rookie draft like current based on record getting what's left over)(only joking...).

I don't have any interest in Launch leagues...so I don't have any opinion on the charge for that.
