Hello,
the customer likes simple but elegant logotypes. Such that are modern, building trust and professional image of the company. 

Font type : Sans-Serif - again simple elegance will win. A great example of a font that the customer likes is the one with the Uber logo. 

Colours: Navy blue (#14203a) ... or burgundy (#980201) combined with gold (#c0a466) and white (#ffffffff).

I would ask you to present the logotype in both colour versions so that the customer can finally decide which colour set suits him better. 

Very reactive and professional. Can only recommend!
