Performing a Website Analysis for Several Websites

We offer digital marketing services to several clients in the Dutch market. Most of our clients are large-scale B2B businesses, and as part of our sales funnel we offer comprehensible and useful website analyses.
These analyses should be operationalized in such a way that every next one should be easy to perform.
We are therefore looking for someone with sufficient knowledge of digital marketing and a bit of design to help us create an operationalized website audit and perform said analyses for several clients.
