Hello, as I can see from the slight description you have posted, you already have a design planned for the application which will be according to the site design.
I have over 6 years of experience working with mobile app development, with my primary focus being on iOS apps. I would love the opportunity to help you with the development of this project.
A couple of questions for now,
1. Do you have the backend services done? If not, should I consider them in the scope of the project?
2. What type of site is it? Does it have a user login section?
I am available on Skype/chat most of the time, so if you have any questions for me, feel free to add me - Skype contact: svegjan
