Your closest options will be Toucan Dive at the Plaza, Photo Tours Divers at Port Bonaire or the smaller Buddy Dive location at BelMar condos.
Lighthouse Beach offers a dive pkg. with Toucan. We dove with them a couple of years ago, they do a nice job - no fuss - uncrowded boats and dive the better sites rather than the closer ones.
I don't know anything about Photo Tours at Port Bonaire. But PB is on the Belnem side of the lagoon so it's a slightly shorter drive than to Toucan.
We stayed at BelMar so I'm familiar with the setup there. Although they have street-side tank pickup, you may only be able to get tanks when they're there, afterhours BelMar guests use their key. The main Buddy location has a drive-thru pickup, but it's 10-15mins. north. I'm not sure if they send the boat down to the BelMar dock to get you either. Not exactly sure where LBR is but BelMar should be within a few hundred feet. I think it's between LBR and Bachelor's Beach on their map.
