Hi,
Thanks for posting this project on Freelancer.
We are a team of experienced web developers from New Delhi - India. The team specializes in ASP.NET(2.0 | 3.5 | 4.5), C#, MVC3/4, MS-SQL, MySQL, JavaScript/jQuery/Knockout, XML, XHTML/HTML5, CSS2/CSS3, Twitter Bootstrap to name a few. I have read the details about the mobile app to book courses and I think it clearly indicated most of the requirements you are looking for.
We can develop the required website using ASP.NET 4.5, C#, MS-SQL 2012, HTML5/CSS3, Knockout and Twitter Bootstrap (for responsive design).
The deadline for the development would be around 15-20 Days.
If you need clarification on my proposal, please send your questions to me.
On the other hand, if you'd like to proceed as I outlined here, you can accept our bid we can get started right away.
PS: We provide a live link to our test server for all the web projects we work on so our clients can have an idea about the progress of the project and they can test the website as it is being developed.
I assure you that you will be satisfied with the quality of the design/coding and the end product. So has been the case with all our previous/current clients. :)
Best Regards
Gaurav
