Hello,
After reviewing the attached file and your project requirements , I placed my bid taking in consideration that the graphics (and I assume the UX) is provided by you, and that there's no need for money management on my side.
When I take your project I will put 15 years of experience working as a back-end developer in it, I'll provide you with a scalable application, clean and documented code, robust architecture, and technical advises.
Although I plan to fulfill all your project requirements, I will also put a lot of options in your hands, allowing you to focus your future work on the project on new features instead of enhancing or editing current ones.
I will provide you with a custom and easy to use CMS, and up to date technology.
If you are interested I can write you a full outlined proposal, detailing the features and delivery stages.
Contact me for any other questions, I promise you that your project will stand out, I am also a very creative person, and I won't hesitate to suggest new ideas to make your project to attract visitors even better.
