I have 2.5 experience in developing web based intellectual property management system for a mobile device manufacturer. Please have a look at my credentials. I have made one system similar to yours very recently. I used PHP, AJAX and MYSQL. It has features like direct upload from Excel Template. Further long SMS (Concatenated SMS, Flash SMS and WEbSMS can also be send). Further, application can also receive SMS and store in Database. Further it also includes features of generating Excel reports. The Excel reports generated have features of automatic graph generation. Further, in case we are required to set the system, charges for bulk SMS sending and Short/Long Code(to receive feedback or reviews from your customers) will be charged on actuals. Mantra: Quality * Innovation = Future Looking forward to work with you. Best regards,
