Trustpilot and other sites can review and comment on the company and product. What I want is something personal, my clients will be able to comment on the service they receive, good or bad. so Trustpilot is not the right place@bugrastar There are a lot of ways to archive this either you create a site and showcase your portfolio, link your site to Trustpilot, create a FB fan page and promote your services, Google my business; there are a lot of ways it's just a matter of searching.
I agree.In that case, you may as well create your own personal website which showcases your work and designs, then add custom forms at the bottom to ask ex-employers how you did.
I don't believe there exists any themes which do exactly what you want but there are form builder plugins which can provide the functionality to allow you to add your own review system.
