Thank you for considering my bid - I'm very interested to work with you. I have experience working with Freelancer clients on adaptations of their novels (I have completed one and am in the process of adapting a historical novel at this time). My budget includes an estimation of hours dedicated to your project (including reading the book in question a several times, preparing a proposal and three drafts of the screenplay). Please let me know if the scope of the project and work changes and I can adjust my bid accordingly if need-be. I cannot submit writing samples via this link, however I'd be glad to submit samples if you send me a chat message.
Thank you,
-John
