check latex references

I'm looking for assistance with checking and ensuring the accuracy of references in a Thesis I'm currently writing. The document is quite lengthy, with over 100 references that need to be checked. Cardiff Harvard Referencing, so the freelancer I hire will need to use their best judgment in identifying which citation style to use for the references. It's an important project, and I want to ensure all sources are properly cited and referenced according to the correct format and check whether the reference exists or no or if its type is even correct (article, book, online..etc). As such, I'm looking for an experienced freelancer with strong knowledge and understanding of formatting styles and reference conventions in order to get the job done right. I am using \bibliographystyle{agsm} for my latex doc.
