Hello,
I'm new to Freelancer. I'm looking for "introductory" projects, and this might be a good fit. I've created a number of demo videos for my own software projects for my company. I would need to have a chat or phone call to learn more about your requirements.
Thanks and let me know if you'd like to discuss further. I would also be willing to do this project on a "satisfactory" basis, which means if you're not happy with it, you wouldn't need to pay.
