Hello there,
I've been a screenwriter since 2010, so I'd be delighted to write this for you. Do you have a video of the two actors who improvised or do you have your written concept that you'd like to use as a basis for the script?
I could do a combination of both: incorporate some of the improvised material into scenes, as well as write situations and dialogue from scratch. It all depends on what you have in mind.
I'd be able to tell you more about my approach to this once I've understood your concept and your vision, as well as the genre.
I have a few pertinent samples in my Portfolio, but I could send you others if you're interested.
Looking forward to working with you. Have a stellar day.
