Good day,
I'd love to start my freelancing with you on this project. With over ten years of experience working with different firms, I think its time for me to become a freelancer and work on my own terms. I really need this project to prove myself and get the best feedback for my future. I am creative, flexible and think outside the box and in case I am selected, I won't disappoint you.
I put 20 days in the project completion rate because I think your bread and butter depends on it like mine does on this and I will be giving attention to details in every way possible so you end up with a premium design that oozes seriousness, elegance and professionalism. I hope you will consider my proposal.
