Yeah Researcher ID wouldn't fit the bill for this.
My suggestion: to avoid the wait for an SRP request, simply get a BAF ID and a Royal Liner for lawful work with Bretonian refugees or get an OSC ID for a Royal Liner or Luxury Liner. Nobody says OSC can't be involved with humanitarian work.
You can still wear a Freelancer IFF without an SRP request.
Oh yes and what Thexare said works very well too.
Not to mention that a yacht, while still expensive, is a lot less expensive than a Lux or Royal Liner.
