product customiser/configurator add on

Hi, I'm looking to use a 2D product customiser on my squarespace store, to allow customers to choose different colour options on the products I make. I was wondering if anyone has done this and has any advice on the subject? 

There seem to be a lot of product customisers out there, but only a few that claim to work on squarespace. One that I found -Brikl- is crazy expensive (€90 per month), where other similar types of software seem a lot cheaper, but don't work on squarespace.

Any help would be much appreciated, thanks

Joe
