Forum:Card Pricing (Help!)

Ok, so a while back I posted a forum (here:http://yugioh.wikia.com/index.php?title=Forum:Old-school_special_summon_deck_%28please_give_me_a_rating/advice%29&s=wl) asking about an opinion on my old deck; and the general impression that I got was that it was good, but needed some tweaking. I'm not asking anyone to build me a deck, but could someone help me with pricing these cards (individually, ideally). I don't know where to go without getting ripped off, so it'd be appreciated. The cards are:

Dark Armed Dragon Elemental Hero Prisma Advanced Ritual Art Reinforcement of the Army Bottomless Trap Hole King of the Swamp Gene-Warped Warwolf Alien Shocktrooper Vorse Raider Tyrant Dragon Prime Material Dragon Solemn Warning Dark Valkyria
