We need a GDPR expert to produce a GDPR policy for our translation business

We have a small translation agency and the way we collect data is very straightforward.

I am more than happy to discuss my business in more detail and provide more information.
We already have the GDPR for web use but its needs to be examine and updated, so that it covers the web users as well as none web user.
Some elements might require updating other may require adding, things like what happens when the three is data breach etc.
MUST BE BASED IN THE UK and must have similar experiences.
