Many here are giving you good advice.
But since you are on a magic forum, I will never tell people not to first go to sorcery to get what you want out of life. From there comes the wisdom from having lived it. Through this process you gain self-knowledge, and then can make informed decisions on who you wish to become in the future.
A Southern Conjure / Brujeria with Demons Approach
For suggestions on what Southern Conjure / Brujeria with demons looks like, see:
JSK Verum: Conjureman Ali - 'Verum Hoodoo Results' (2011)
This as a legit alternative approach to working a full evocation, that resembles more a Folk Catholic Novena. Get their photos and put them in a glass jar with sweet syrup to make a Sweetening Jar . Glue the seal on the demon on the underside of the lid. Read up on African- American Hoodoo / and Latino Brujeria for other herbs to add, but also not really necessary. Don't use honey (making it a Honey Jar) because honey is "slow" like molasses. Use syrup, which is more fluid.
Just because the Grimorium Verum is my deal, burn a tea-light candle on the lid, another one for the demon, and extra tea-lights for any of their superiors up the Infernal Hierarchy that are called to 'get a handle on them' , and use the Astrochios Prayer to call them. Do this for 3 to 9 consecutive days to "get their attention" if you don't already have pacted allies standing by. Say want you want out loud, with your voice. For a number of reasons.
Even if you do not see or hear anything, assume they are listening and checking you out. Complete the ritual as if they are there. And honestly, they will be. Even with these simple little cantrips. Your expectation here is big part of part of it.
Learn to listen and give them something in return. The candle in the jar is part of it, but there may be more. A pissed-off demon is not something you wish to deal with. Tell them what you want, and what you don't want (meaning give them constraints ). This second part is very important, and don't listen those who tell you it hurts their feelings.
Demons tend toward overkill a bit, like launching nukes at a mosquito. But you can mitigate it by giving them constraints. Tell them out loud - do not assume they can read your mind - what you want and do not want. I have made the mistake of conjuring them and just turning them loose, no-hold barred.
Again, the nature of the spirit you call will "flavor" the working and the entire region in their wake. Do you want that kind of influence? I once called the hot Petwo Lwa, Met Kalfou, to deal with meddling in-laws, who then promptly crashed their car and were injured more than I wished. Do you want to deal with this kind of outcome?
Sorcery with hot spirits is like a gun. Don't point it unless you are going to "kill" someone. Not literally, but that is a real possibility. Mitigate that a bit by telling them very straight forward them to like, NOT, do that. It is your reality they are playing in, not you in theirs.
