I am having 20 years of experience in web based project development. I have designed various project similar to this bur on a larger scale having the executable value more than 10,00,000/= I presume from the initial price that you have a small activity and such presumed your requirement, hence quoted the price. Once we discuss the project I will give you more realistic price which may be lower or higher. Please be assured I can give the most suitable solution at affordable price.
