Dear Sir,
my name is David Abraham and I'm a freelancer with 24 years of experience in freelancing, internet research, web copy, translating, programming websites and translating them.
I have read about your needs and, given my strong background in the field, I am pretty confident I am the right person for the job (this also thanks to my strong knowledge of the web and to the fact that I am a relentless hard worker who stops only when he gets to the results he has set for himself).
Feel free to contact me with all the needs related to your job offer, should you find my offer for a long term collaboration as being interesting.
Looking forward to your always welcome reply,
Kind Regards,
David Abraham
