Ask HN: Selling IP fast and conveniently

I am looking to sell the IP of my company. It consists mainly of quite generic source code for ordering cabs via smartphones, client+server. The IP has been in use for 120000 users and is quite mature, the released apps are rated high. Problem: the company wont make it far, due to recent contractual events. I want to sell the IP as fast and convenient as possible. Any ideas ?
