Dear _____:
Over the past two months I have had several different companies apply for my labor. After considering all of the offers, I regret to inform you that I am unable to offer my labor to your company. Although you may be disappointed that I am unable to accept your offer at this time, you have my sincere and personal wish that you may be able to find an equal EMT elsewhere.
Sincerely,
