Hi @patriciamakstudio,
Thank you for reaching out, we do appreciate your time.
Unfortunately, custom markers are a Pro feature and as a result, I will need to ask that you reach out to us directly on our website to discuss the options available. You can do so on our website by clicking on Support > Support Desk > Submit a support Ticket.
We are not allowed to offer any premium support via these forums as they are reserved for supporting the base version of the plugin, as per the ww.wp.xz.cn guidelines.
Note: This thread will be marked as resolved as it is specific to our Pro add-on, and under the ww.wp.xz.cn guidelines, no premium support is allowed via these forums.
