From the custom branding article:
"For paid jobs, the web viewable versions of the maps can have the users company name and website link in addition to a linked version of their logo. For free jobs, the Maps Made Easy logo will be displayed but the users company name and URL can still be displayed in the attribution."
If you want to display your name and logo it has to be a paid job. You can either do it on a subscription or by paying with points.
