By far the cheapest option is to reserve van-size taxis to transport you all to the Fajardo ferry terminal. You'll probably need at least three vans, especially if there's lots of luggage. They will cost you around $80 for each van, regardless of number of people. It takes 50-60 minutes to get to Fajardo from SJU airport.
The ferry is only around $2.50 per person.
Once in Culebra, you can use publicos for $2 per person for the main routes. They can sit 10 people or so. They run regularly to and from Flamenco Beach.
All in all, these are remarkable transportation values for a large group of people. The only way to do it cheaper is to walk and swim.
