Hi Mark,
I tried to visit your website, but it appears to be inaccessible at the moment. Regardless, if possible, I'd like to view (read) the script first, before discussing this project further. That is because I'll then get an idea of how much change is required, and therefore how much time it'll take me. I will then be able to quote my fee and time requirement accordingly.
Once I've understood that, I'll need your comments on what you like and dislike about the script at present, and I'll work from there.
Now, a little bit about me. I'm a writer, and I've been writing professionally for a little under a year. I'm a college student, and work part-time on Freelancer (and some other freelancing websites). My strong points is writing informally - whether it's blog posts, a candid interview, or a humorous product description. However, I've dabbled in various fields, and written a lot of different types of content, such as advertisement material, website content, sales scripts, marketing emails, newsletters, articles, stories, books, and some others.
I generally have a turnaround rate of close to 1000 words a day (plus a little extra for proofreading), so that may help you determine roughly how long it'll take me to work on your script. If you'd like to know anything else, message me.
Thanks,
Priya
