I want to reiterate my willingness to teach any course needed in [Field 1] this coming year. I am prepared to teach courses in [listing of numerous areas in Field 1], as appropriate to my preparation and training.
I'm open to discuss any and all possibilities with you for the coming year. Recent teaching experience is perhaps the weakest link in my CV, which I wish to remedy, and seek your assistance as a recent graduate.
Attached is my current CV. Please contact me at your earliest convenience to discuss this matter.
I thank you for your consideration and continuing support,
