Auto to manual

How hard is it to make an automatic 97 civic into a manual? i'm doing a b18 engine swap with a manual tranny is it just a matter of different shift linkage and a shifter? or is there more to it than just that?

And, any idea how much $$$ it would be? Just a guess

this guy at my work said that his friend 99 civic was an auto.. he took it to this guy who had a 99 civic manual and they just switch the transmission. so now he the same civic but now a manual. the guy was a friend of him. so he only charge him like maybe 200 dollars... so i dont know
