Hi Sir, I hope you are doing well,
I've carefully read the description you provided. You can expect 10 banner designing for your online store to be eye-catching, classy, professional and beautiful. I am experienced and worthy enough to take down this job.
Please send me the photos and other elements and I will send you a sample, I am sure you won't be disappointed :)
I really look forward to winning this bid and start working with you straight away. I work efficiently and at a great pace. I take all my projects very seriously as if they are my own. My work is always of very high quality.
My attitude towards work is very professional and realistic.
You can view portfolio in my profile.
Thanks and looking forward to speaking with you again soon,
Sam, Graphic Designer
