subscription model and invoice template ?

Hi Envato team, does our government owned company (actually state office) need enterprise subscription, or would it be possible to go with simpler team (up to 5 people) licence ? (company has 1000+ employees, however, the PR team are actually no more than 5 people, remaining 1000+ co workers have their own businnes, completely unrelated to pr/media),
thanks, and second question - could you send me example - template of invoice, which is required to be checked by billing team, to even allow pay for your product (subscription). (government owned organizations have very strict rules) Thanks, Radek
