I'm willing to pay $175-250 for this work. it must be done in 21 days or less. You can use as many plugins as you want. I'd prefer it to be in drupal, but joomla is also a possibility.

My client needs a portal will be created for our clients to sign up and run campaigns or we will create accounts and run campaigns in our clients behalf:

Lets say I want to run a coupon campaign like this: Send COUPON to [obscured] or Sub-keyword Send COUPON STORE to [obscured] to get 15% off

Mobile device owner can now send a text to [obscured] with COUPON in the body

Mobile device owner will now get the 15% off coupon send via SMS to his device and can redeem it at the POS with a coupon code

THIS 3 OPTIONS NEED TO BE RUNNING AT THE SAME TIME! IT WILL BE A DIFFERENT SETTING DEPENDING ON OUR CLIENTS NEEDS AND BUDGET.
Send and receive messages throughout a SMS gateway like clickatell.com
and
Receive SMS on a GSM modem and send the keyword response message throughout a SMS gateway like clickatell.com
and
Receive SMS on a GSM modem and send response using same GSM modem

Create unlimited keywords and sub-keywords for campaigns

Export, import contacts (all or per keyword, sub-keyword)

Create reports

I would prefer a CMS solution such Drupla or Joomla to base this on. Both platforms have some SMS modules you could build upon.

Installation design and all that will need to be done.

Attached is a mock up of the user front end.
