Other posters have already gone into the typical warnings against direct love magic and the absolutely on point advice of instead working attraction magic so I'll give you some practical advice.
All the great tomes contain multitudes of love spells. Pick one tome and master it. I prefer the Picatrix, that one has tons of love spells, but I'm good with the spells because I've worked that book so much I understand the unwritten mechanics in it.
Venus and her spirits are going to be who you are approaching for love, Mars and his spirits to ignite passion and desire. There are demons, angels, djinn, daemons, all classes of spirits in every tome that are associated with the planets so if you can get ahold of a spirit associated with those then ask them for help with whatever you're trying to work.
As for love magic directed at a single person, highly unwise, always backfires, and it's ethically suspect as hell, but we are magus and ethics are malleable in our realm. So if you must you're going to need a sympathetic connection to that person. This can be an object of theirs, a calculation of their chart, or even giving them an object that acts as a link. Martian associations to ignite their desire for you and Venus associations to make them enamored with you.
As others have warned though if you single out a person for love magic you're gonna have a bad time.
