It sounds like you are looking for an extraordinary spell, but yet other people might recommend you this sort of spells if they have found it elsewhere.
Here is my recommendation for you:
You are begin specific with your spell request and it's category, so I think that it will be hard to find such an extraordinary spell here.
You are also making your spell request more specific and extraordinary by adding to your request that you need a spell that involves blood sacrificing since you find it as more effective. This request and sort of addition makes finding this extraordinary sort of spell even harder, almost impossible (yes, the word impossible is too big, but this is a term we use many times).
If you are specific, I'd recommend you to make your own spell for this. It will make anything much more simple because you'd write this spell for your own will, and you will make it much more specific (just as you want and need). You will also be able to express exactly what you want.
Also, I find my own spells as much more effective and comfortable to use. I have said one of the reasons above.
I'd also like to add that this is being expressed and comes from your own energies, so it suits you specifically.
It is much better to cast a spell that matches to your own will, desire and intent specifically.
May god bless you,
