Script amends

Hello - I am looking for a script writer to make amends to a script. The script has been partially approved but some notes from the client will come thru in the next week or so. I need someone with experienced in scripting for reconstructions/piece to camera short films.
Once shared the client's notes, the amends need to be made pretty quickly within the day or following day max.
Must be based in the UK and proven experience in scripting.
Thanks.
