Its for 1990 535I with an M30 3.5l engine

I need to replace my oil pan gasket, i went to the mechanic shop the guy said he cant do it, u have to lift all the engine up or take the whole front out lol, because the oil pump is in the oil pan. Is that true?. I can do the job my self but im not sure if u have to do all these things. Can i do it in my garage or i need a car lift? And the bolts on drivers side are pretty hard to get too.
