Pay rise letter

I am looking for a talented freelancer to help me write a pay rise letter. The purpose of this letter is to request a pay increase, my desired salary amount has already been determined, and I need the final product in an email format. The successful applicant should have a good understanding of workplace rights and salary negotiations, as well as an ability to carefully craft a persuasive and effective letter. I have a set budget and timeline in mind, and am looking forward to seeing the creative services a freelancer can provide. Thanks for taking the time to read this, and I look forward to working with you on this project.
