Hello,
I read your job description. Although it is not in details, I am interested to do this job for you. I need to discuss the project in details. My price is an estimate. I will give you my final price when the job is clear to me.
I will write the program in PHP. I am considering other solutions which does not require coding. But everything depends on your job details.
I need to know what is your email server. Do you own the server or you have an account and wants auto responder for that account.
Looking forward to chatting with you over the project.
Regards,
Ara
