Here you go. Proficiencies gained and when your 5th level extra attack kicks are the main determinative factors for planning your multiclass. That doesn�t really apply to you, so you can really just do them in whatever order you want.
If you are planning on abusing eldritch blast with quickened spell, you should start warlock, level it to 2, then just focus on sorcerer for the rest of the game.
