Can anyone recommend a freelancer to help with our integration?
This community focus on clarifying and solving particular technical situations related to Auth0 and authentication/authorization concepts. Participants are either interested in looking for a solution to a very specific problem or interested in helping troubleshoot technical issues. It’s not the best place to look for freelancers and as such I’ll have to close this question.
I would recommend you to search on sites that are dedicated to providing freelancing services, in particular, developers with knowledge in Wordpress/PHP and authentication in general should be able to accomplish that integration.
