Prepared technical specifications for website promotion, who should I give for examination?

Question

Search Engine Optimization

At the request of the client, he prepared a TOR for website promotion in the Yandex search engine, the region "Moscow and the region".
The site has been with the client since 2010, has a decent audience and quite good positions, so neither the client nor I would like to take risks.
The question arose: to whom can a draft TK be submitted for examination (for a fee, of course).
How and where to find an expert? what parameters to pay attention to? how much would such a service cost?
