Hi There,
Thank you for writing in, you can try the WP Cost Estimation & Payment Forms plugin that is bundled with X and PRO theme. You can install it under X > Overview > Extensions
Estimation & Payment Forms
There is a TOPBAR area in the X Theme where you can put your Contact Number and Links to your Social media pages. You can enable it under X > Launch > Theme Options > Header, find and turn on the Topbar and put your contact number on the TOPBAR CONTENT.
Social media page links can be added on Theme Options > Social, leave it empty if you don’t want any social icon links.
Hope it helps,
Cheers!
