I need to acquire Hip Hop/Rap instrumentals from a music producer

I'm KayMatters (A Hip-Hop recording artist) and I would preferably like a Hip-Hop/Rap/Grime music producer from the UK to acquire beats from. The producer should have a professional sound and if not have studied music should have mastered their sound. The beats I'm interested in should not have been used by other artists and I like everything from soul-sampling beats to hard trap soul 808 beats. Also, the fixed rate I'm looking for per beat would be between £40-90 (If costs less and sounds professional, I'm not complaining lol). Last but not least, a portfolio/showreel snippets will always signify the type of producer I'm looking to work with.

Thanks
