Dear Madam or Sir.
I would like to show my interest in applying to the said position as a customer support worker and translator.
My English knowledge as well as my Swedish knowledge are an ideal match for you.
I'm used to both customer support and translating, having done both for several years for an Swedish organization.
A couple of my strongest suits are being a responsible, devoted, reliable and genuinely interested guy with a love for writing!
Please consider me.
Best regards,
Nelson
