advice Retiring

I've retired from my real world employment and have decided to also sell the bulk of my domain portfolio. Currently at Uni but I plan to remove them soon. The portfolio is currently around 950 domains, primarily .com, also some .net., org and a few .biz, .info and .us. Most of the domains are between 15 and 20 years old (i.e in my possession)., and generic 2 word domains or i or e prefacing one word domains. A small handful of purely one word domains. What would be the best persons, places or companies to approach with my domain portfolio? I'm not in a hurry but would like to start down the road to being foot loose and fancy free with my time and money. I currently don't have a firm price in mind and am willing to entertain offers. Any advice?

Thank you for any input.
