How do I make it so when you type in my squarespace web address it instead takes you to a new weebly website I set up?

I have one old portfolio squarespace website at www.andrewreffmultimediaproducer.com that I split into two new portfolio websites. When I apply to a job I give them one of my new portfolio web addresses that are hosted on weebly but there are still some jobs I've applied to that have my old portfolio website address. 

So when they click the link for andrewreffmultimediaproducer.com I want it to immediately take them to https://www.andrewreffdesign.com/portfolio-options.html instead. I've tried all the options URL mapping codes I've found online but none seem to work. Can someone who know's what they are doing help me write a code that would work for this? Thanks in advance!

Click on the link andrewreffmultimediaproducer.com only

or click on that link + all link andrewreffmultimediaproducer.com/*** will redirect to /portfolio-options.html site?
