those domains probably wouldn't be considered premium, hyphens generally reduce value significantly. I'm not an expert on this, but I have looked at auction closing prices. Also, domains that sell high, that aren't GREAT name names,were usually promoted heavily or marked by a domain broker who works hard to make targeted sales. If you find the right buyer, it's possible, but it probably won't be easy. If you want to make money parking them, I would suggest not using sedo, as they use adsense, and split the earnings with you (which means you'd get more setting them up yourself). Sedo parking is generally only if you don't feel like setting them up yourself, or don't have hosting, or don't have an adsense account, etc. they just make it simple and quick, but they do NOT drive traffic to your sit. If you aren't already getting hits, parking probably won't help. You'll have to search "domain parking" if you want more info. I would suggest setting up autoblogs or something like that if you want to monetize them, and maybe even put at the top of the blog, this domain/site is for sale. If you build them into sites, and you think the domain names have high a value, then even without traffic, it's possible that they could sell on sitepoint because of the domain name. I honestly don't see the domain name alone drawing in a high sale price, but like I said, I'm not an expert, I don't know. Good luck
