Also a word of warning, if you find a motor from someone nobody's ever heard of for a great price, there's probably an 80% chance your going to get screwed. Either missing or damanged parts (shift linkage, mounts, axles, ECU ...) that are going to blow your budget up past what it would cost to just buy a complete motor from a reputable company (I don't know anything about the company you posted and their manual price is reasonable but I've personally never seen an automatic B18C1 setup before so that makes a little fishy). Save your money, do it right the first time, trust me.
