Dear Sir/Madam,
I am applying to your job posting and I'm very motivated to work on your project. I am 'entry level' as a freelancer but I have 10+ years working experience for many foreign companies. I will arrange all relevant data so you can find them very easy. Also, if you have any request about template design, cells or column or rows colors I can do it for you.
I hope you will take me into consideration and give me a chance to show you that I will do this work for you responsibly and precisely.
Looking forward to working with you.
Sincerely,
Ivan Rankovic
