Need help in Writing a custom script to add hyperlinks

Hi There, 

Can I ask anyone's help in writting a script for me? I know nothing about code and need to do something that seems accessible only through script in Indesign. 

I would be more than happy to pay for your time and expertise and helping me setting it up. 

I am building an interactive presentation in Indesign to be viewed once published online. I am making a template now so I can fill it in with all of my pictures and text with Data Merge each time I need to update this presentation.

And I would need help in writting a script that would : 
Once merged, add an hyperlink to each page opening up this specific page only in a differents tab ( as a cheap way to select an image showed on this page ). I can add a shape to the template to be made into a button once merged. 

If anyone is interested in helping me out it would be great !! 
Thank you so much ! 
Maria
