Dear Sir or Madam,
I'm interested in your offer!!
Actually this is my first offer as a freelancer, so I will give my best to prove my skills!
Working in excel is on my daily bases + I made my bachelor + Master thesis.
So I believe I will be pretty useful for you.
I believe in two days I can handle your request quick and without problems.
So If you are interested, let me know and we discuss it.
Looking forward to hearing from you.
Best regards,
Martin Zundalek
