Add Coding to Websites

I need someone to add some code to our websites. We have various pieces of code that need adding (google analytics, trust pilot, A Weber sign up form and possibly a few more bits). I need exceptional communication skills and the successful freelancer must be able to work with minimal instruction and just get the job done. I suspect the work will take no more than 1 hour. There will be more work for a goo freelancer moving forward.
