Looking for a Web Developer in ASP.NET 4.5 to develop modules for an existing application

I am looking for development of few web pages will be later integrated into an existing application. The details of the project are as under: Langauge: ASP.NET with VB Back End DB: Microsoft SQL Server 2014 UI Interface: Devexpress (if 3rd Party UI Interface is required to be used) Total Pages involved: Not More than 20 Pages (3 Modules containing approximately 4 to 7 pages per module) Each Module will contain an Add data Page, Edit Data Page, Update Data Page and View / Search Page. In some case, the amount of data involved in the View / Search Page may run into about 50,000 rows. Hence, the View / Search UI should be able to support such large data handling capacities. All pages will be stand-alone pages in the standard format with no major design element except to support the UI Controls, Text-boxes, Comboboxes, etc. All pages shall be integrated into the existing application which uses master page control, hence, control which causes issues while using master control should be avoided. Further, you are also required to create a stand-alone app which will be installed on the client system which will act as a bridge between the web app and file system of the client machine. To briefly put across, the web app will provide a network file share link, on clicking the same, the client system should automatically open the file or folder in Windows Explorer so which we need a bridge app. The Data structure, inputs column details, datatype and relationship chart will be shared by us.
