Turnaround is typically 10-14 days. If you need your feedback faster, you can purchase Rush Services, which offer 24 hour - 72 hour turnaround times for an additional fee. Basically, this is overtime for me as I'm fully booked.
I'm a working professional reader so I know what buyers want. There's no point telling someone they have the next GET OUT on their hands when they don't. I'm very honest in my recommendations and rankings on my cover page, but my comments focus on how to improve your project. I consider myself to be part of your team.
Email me your script to Amanda@scriptgal.com, and tell me what service you are interested in. I will get back to you with my availability. You can then purchase the service here, or I can send you an invoice.
