Dear Mr. Garcia,
I am responding with this cover letter and resume to your advertisement on www.dice.com for a Volunteer for Peace Corps to help with administrative and operational tasks.
There is not a cause I am more invested in than that of animal welfare. I love animals, and see that there is a huge discrepancy between how many loving homes there are to house them and how many animals are present in this state. I would love to help with this volunteer effort. I am conscientious, take all jobs seriously, and am committed to helping in any way I can. Moreover, I am planning on becoming a Veterinary Technician in the next few years, and would love to bring this fulfilling experience to my career.
I look forward to hearing from you at (555)-555-5555. I can meet with you whenever your schedule finds it most convenient. Thanks so much for your consideration.
