256819 SMS /email INFO on Demand

I am interested in setting up an sms to email based information on demand service . Basically it will be an SMS Brochure Service/Application and people just make request through sms to get product brochure and even account opening forms via email. Basically a service that allows the GSM phone user to send an sms message to a number including a keyword and their email adddress. When they do this they will receive a digital brochure that could be a PDF or word document or even an HTML email in their email inbox. And also receive an acknowledgment text message. It will be a multi-user. And Self [login to view URL] potential advertiser will sign up and will be allocated a user interface that will allow him to upload or create the document that will emailed back and also allow him him to edit the content of the aknowlegment text sent back. There will also be option for a simple text back option(without sending an email) The advertiser will have be able to see all the incoming text messages at a glance and will be able to send follow up text message and maybe emails to them. At a glance the Advertiser will able to see all the responses generated( gsm number and email addresses) and will be able to either export them to send them follow up messages or will be able to send follow up emails or text messages from within the application. Billing will be done by selling the advertiser a block of credits against which the auto generated reply text will be charged(this will be allocated by the admin) Programmer must configure it in such a way that I can use any major sms gateway for sending automated reply text/sms messages The system will need to receive sms messages from a gsm sim card hosted somewhere and configured to send received messages into a web application via different protocols Also the reply text/sms messages will be done by buying messages in bulk from a bulk sms gateway of my choice. Please in your response let know know you understand what i am talking about. I might request a simple basic demo. Similar services doing this are .
