Good day. I don't know what development stage your script is in, but I've been writing comedy and drama for the past 20 years. Let's see if we can put a draft together.
Relevant Skills and Experience
20 years of screenwriting, but more importantly, writing in other genres; copy, stage, fiction and children's books. I believe this helps create a platform of constant creativity, keeping things fluid
Proposed Milestones
$50 USD - first 10 pages as a rough draft within 3 days.
$50 USD - with your approval of first ten pages, the next 10 pages
$66 USD - completed script within 3 days, pending your approval
Additional Services Offered
$1 USD - voice over-if needed for narration
Thing is, when you say "various roles", I still can't get a breadth of the scale here. Are we talking a short script; 10-45 pages? Or something more grand; 45-115? Specs always give a little more clarity, because screenwriting is very time consuming.
