Dear Sir,
I'm a software engineer and have a good solution for you as I've already finished such project.
My solution is built on a Outlook plugin and then scripting vba to communicate from each other (Access-Excel-Outlook) if you also need to import Excel Data to send an sms.
I want you to be sure that I'm able to do your project, so please, see this scenario :
1- Let's chat through freelancer if you can give me additional information as it's really important for me to know if you already have an sms provider
2- I do the job WITHOUT any commitment/award/milestone from you before 6 days (give you a way to test remotely with real number for sms)
3- Once the test satisfy you, then you award me the project and realease a full milestone.
4- I'll send you the full scope project as soon as you award me the project
5- When the project is done, you give me a good review as it is the most important thing for me. (I like to satisfy all my employers)
6- I'll give you assistance during long terms business for bug free or if you migrate to MS Office 2013 one day.
Thanks & Best Regards,
S4.
