Hello,
I am experienced in programmer and will be willing to work to complete your task without any risk to you. Pass me the job and I will complete it after discussing the details with you. I will hand over the project back to you without any payment or commitment from you too. I do this because I would like to get the opportunity to work with you.
Also I have not worked with Facebook Appointments before and this way if I am unable to complete it you loose nothing, except the time you devote to me to explain the problem :)
One request that I have for you is that, once the task has been delivered back to you, you award this task to us and complete the payment.
Looking forward to working with you.
Thanks and Regards,
Vinay Samtani.
