Hi,
I can write a script to query API to get quote, shipping company and delivery time.
Script can use data from excel sheet.
I have expertise in PHP, HTML, Wordpress, CSS, MySQL, JS.
With 5+ years of experience in web development, I believe that I am a perfect candidate for your requirements.
I will not take much of your time and keep my proposal short.
We can discuss more over chat.
Note: Actual quote will be provided after complete discussion.
Thanks
