If it was me the first thing I would do is get him gelded. Young horses are just not selling these days, and this time of year is also not good because it will be getting cold soon and people just don't buy as well in the winter.
If you can afford hay for them I would get him gelded and as soon as you start needing to hay them build a small temporary corral and work w/ him all winter, just the basics would be good, leading, loading, handling feet, etc. this will get him use to being handled, and use to being separated from mom. I don't expect prices to come up alot between now and spring, but alot more people will be looking and maybe you'll be able to find someone that wants a nice young project horse. Generally people want a horse that's had age appropriate training.
