There are lots of jobs out there right now and retired airline pilots are definitely getting picked up. I'm in Norfolk and about half of our local pilots (most hired in the last year or two) are recently retired legacy.
Your best bet up in DC will be Manassas (KHEF). There are a few operators there that have been posting jobs pretty consistently. Chantilly Air comes to mind.
Also, as others have said, flying is very little of the job on the 91/135 side. You have heavy experience that is probably mostly international. That's great, but it does not qualify you to be a Gulfstream or Global Captain. Especially since you've never flown on the business jet side. There is a lot of coordination required for International trips that you have never been a part of. Aim for a position as large cabin SIC or small/mid PIC.
