bleh depend on what server u play on.
On my server, the quest is in LHZ city, u go the way u normally would to enter the biolabs, but keep on going (don't enter bio labs) talk to a dude in the lab room in a corner whose name starts with a C or something. Then go to LHZ hotel, talk to another dude, then go back, answer 3 questions, answer might vary go google it. Then he boot u out again, go find his son, talk to his son then go back to the lab again. and he finally teaches u the homun skills.
Go to alde alchy guild, buy the stuff like glasstube, dew of yagg and seed of life, plus a med bowl. Have your pharmacy and potion creation maxed and best if ur stats are all on luk/dex then just use pharmacy.
Some servers require a homun creation guide, is usually sold in some shop in the main city of your server.
Ok i just debriefed the annoying quest down to a paragraph...but go on search engine websites and do some search, is easy to find a guide. They even have pretty pictures to walk you through the process
