Hi there,
I would love to be considered for this project. As a student, I am always looking for additional avenues to increase my income, and I think you could benefit from my services as well.
Barring all the tasks you mentioned relating to Craigslist (which I think I can learn), I have a considerable amount of experience as you can see through my feedback.
Ironically, my favorite hobby is being a part time virtual assistant (another reason why I think I am perfect for this project).
Since I am a full time student, I prefer taking on jobs where there is a little bit of flexibility. I feel I should warn you (before you consider my bid seriously) that there may be days on which I am unable to work at all due to a difficult course load. Having said that, I have never missed a deadline that I have agreed to in my life (freelancing or otherwise!)
If you have any questions for me, please don't hesitate to ask. I can provide a sample of my writing if you need to see it.
Sincerely,
Abbas
