Question about Enfold WP theme

Hey there, big fan of the Enfold WP theme. Likely going to purchase it, as it’s a great fit for the website I’m going to set up, as I’m looking to start a small company. Just a few quick questions to run by you.

-Can I replace the header text on the left side of it with a header logo image? [like in one example, I’m looking at the text “Enfold portfolio” on the left side of the header.

-What are the dimensions/size constraints for a header logo if I can insert one? I’m currently having a custom logo designed by a graphic designer, and we were discussing sizing, so I want to make sure they can make one to fit your template.

Thanks!
