Carpentry help?

im looking to build a loft area in a bedroom, and I was going to do it myself, only i really have no idea what im doing. i want to make a 6x9 loft at about 5 ft high, for a bed plus storage area. I was trying to find carpenters here in eugene that I could maybe hire, since I dont know what im doing. but all the carpenters I've been able to find either do like full houses, or decks and fences. I know that this is a relatively small job, and was wondering if anyone had any suggestions?
