I need a network engineer to fix some CAT 6 termination boxes

I am getting some house renovation done, as part of which have laid Cat 6 cables at 4 different points originating from the point where my broadband router is located. I have also laid out 3 optical fibres in a similar way (more for future use).

I am looking for an electrician who can install termination boxes at both ends of these cables. The Broadband router end will need a 4 gang + 1 gang for the Cat 6 and then 1 gang each at the 3 end points and a 2 gang at one end point . Similarly need 3 optical cable end points fitted. (if you dont do optical, am ok for just the Cat 6 to be done.)

I am looking to install the BG Screwless brushed steel faceplates.

Can you please provide me an estimate and also your availability ? I live in Eltham (SE9) in South East London.
