Typographer for small website design and marketing business

I run a small website design business/marketing business (I use a quite few agency friends and freelancers in graphic design to deliver) however I really want to improve on our typography, this is one area I want to improve during our project delivery. Do you have any costs/rates? Usually I provide my client with a set (heading ,subheading, body ) normally 3 set variations inline with logo/brand.

At the moment I’m only dealing with small/ medium businesses and do not need a "newly design font" but someone who understands and can put together good typography for the brand. Also please let me know / show any previous work for this area?
