Different pricing for each size?

Sorry, I know this should be straightforward but it's stumping me. I'm doing a website for a artist who sells prints of his paintings. Each painting is sold as a poster ($12), flyer ($, postcard ($6), etc. I have those options in a Characteristic dropdown. Also a Characteristic dropdown showing the choice of Matt Finish ($0) or Gloss Finish ($5 extra). And so on.

Am I able to apply a separate price for each Characteristic in the Starter version, or would that require custom fields therefore the Essential or Business?

Thank you,
Wesley

Can't believe I was skipping right over that, thanks!
