black metal song created

i have a one man band thats dark ambient horror. im looking to insert some audial extremity and fury into some tracks so need to have someone who can play and produce a very heavy fast and insane 2 to 3 minute segment similar to Anaal Nathrakh in style of black metal/grindcore so u must be able to produce fast loud pounding blastbeats and extreme guitars. the idea is to have something that builds on dark atmosphere and then bursts into heavy blackened metal. i am creating my 2nd self released album and want to insert it at end of one of my ambient horror tracks. i will figure this out later i just need u to record a solid extreme modern black metal segment as i cannot play. i dont have much money so u would b helping a fellow musician out. can pay max £20 at end of project, i cant pay by awarding as have got stuck in this before so i need to know person i choose is understanding and on same wavelength as me. i need progress files sent to me and easy quick revisions done if its not to how i want it. if this is cool type MUSIC at start of message this may lead to future work so i look forward to working with u
