Hello,
I am an engineer and I can help you. In fact, I have done similar projects involving mailchimp api, like https://www.freelancer.com/projects/Python/Write-some-Software-10019300/
I can even provide you with a prototype before we get started. if you are satisfied with the results, you hire me and I give you the script, if not, you can still hire someone else.
To better help you, I would need additional informations :
- what language do you want for this project? I would recommend python, since it has great modules for mailchimp, but php or other language could work too.
- in what mailchimp list should be stored the information ? should I create a new user in the mailchimp list or just editing existing one ?
I hope we can work together. Please send me a message if you are interested.
Best regards
