We really know that you need a fast completion of your website. However, we could give you more by giving us a more time. Our design would give your website maintainability, scalability, and quick performance.
As we mention 28 days as our deadline, we are using scrum methodologies. We will give the iteration as quickly as possible, if the website mockup had been completed in one week. We will give it to you immediately and we could continue improving the website on each iteration.
The features you specified will act as a base feature, if you ask feature that is more than 0.3 value of complexity. Extra prices will be added.
We are working on a centralized team, we would like to help you.
