Placing 1 Facebook ad set - Urgent

I need someone in the UK who can take control of my screen and place a set of Facebook ads into 1 ad set for me for one of my clients. I was working with someone to do this but they are unfortunately now unable to see the task through and I am floundering! I have the copy and the images all ready to go - just need someone who can tie it all together of FB for me without logging into the account from their PC as some of my clients have lost access to their FB accounts recently as I tried to get remote help for them.

I know there is a FB pixel installed on their site but I can't find how to find it and add it to the ads. This is probably not helped by the set up of our FB ad manager (set up by a previous member of staff.)

Looking for someone to help with this urgent project with a view to handling my future client requirements for ads
