As you say professionaly ..... it will show up some financial problems ... theres no central Organisation interessted in Bitcoins future that could spend anything. Lobbying and PR usually costs money (or Bitcoin). Therefore an Organisation is needed to coordinate this. And this Organisation will depend on donations.
My first Step, if i were a guy with background in PR lile you, where to find some other guys with PR Knowledge and Expierience. Found an Organisation, a Website and get Donations. Then making tactical discussions on the net.
I like this Idea and i think interested Companies that are in Bitcoin allready would do some donations. But IMHO at first you need a Concept for this PR-Group itself. Maybe it will be something like a Companies driven Interest Group (B.I.C. Bitcoin Interrest Group!). Once you have Money, you have what you need to start tactical Campaigns.
I would welcome such a Group, but someone have to take this serious and on a professional manner like you said.
