don't follow guides. guides are ok when they are released, but for every day passing from that point, other people read the and use the AH with that in mind. use a site like http://wowhead.com and check recipees for the profession around your level, check AH for cheapest mats and save a fair amount of gold. sure, it'll take you longer than using a guide, but you can save a lot of gold on it aswell. (take it from someone who's got 4 chars at 450 jc kk ;D )
also, check the AH for the items you're planning on crafting aswell, to see if you can actually make some money back on them..
the 210-250 range is usually a bit expensive on some realms, but there's ways of working around it obviously... anyhow, easiest recipee at 220+ would be http://www.wowhead.com/?spell=26876
