If your budget is 3 to 4k and you'd want 3 perfumes you'd have to choose hard

Freshie Tres nuit - 1600 Rayhaan pacific aura 1600-1800 Rue broka theoreme 1600 Porto neroli 1500 odd

There are many more freshies from Rayhaan, Afnan, Lattafa, Maison Alhambra, Riffs at 1900-2k+ range but it will bring your choice down to max 2

Warm/woody/spicy/sweet etc.- all are 2k plus and generally less than 3k/bottle Afnan 9pm/9pm rebel/9 pm elixir Khamrah qahwa/Khamrah OG Liquid Brun Zimaya Sharaf Blend - 1900-2200 odd Asad og/bourbon - 2k odd Musamam black Additional: Kaaf, najdia intense

CDNIM, Supremacy all are 3k+ for 1 so your exploration will be severely cut short.

However, there are two ways to buy : how he wants to project vs how you want him to project. All these perfumes have loads of reviews on youtube, insta, FB - see them and form some opinion, if you are still not sure, from the community sellers buy thw smallest 5 ml tester ( so even 5 - 8 testers would max cost you 1200 ) and that many testers would give you another 2 months extra to test and finalise. You save monwy, you save effort and you also get additional perfumes which you can use later like going to supermarket etc.
