Need mobile responsive design in bootstrap from existing asp.net webforms portal project

I've built a portal into an existing application I wrote and used bootstrap for the menu and layout. While my overall software design skills are pretty decent I lack skill in responsive design and the portal needs to work correctly on a mobile device that is scaled appropriately to the viewport size so the the end user can fill out the application on their phone without zooming in and out and have the menu's work correctly (presently they disappear on mobile). You can see the portal here: https://corpsnet.ctwfl.com/ login with tester7.test7 Password567 As the present portal is built in asp.net webforms I'd like to keep it that way and just adjust the css and bootstrap. You'll need to modify the master page and the CSS. At a minimum get the menus working and get the application page responsive and if possible fix the signature box (super signature) so that it works on mobile. You'll need SQL Server and the latest visual studio - I can send you a stripped down version of the database and ASP.NET application. I can't vouch for the overall quality of the existing CSS... It will take a day or so to organize that and get that over to you. Would not hurt to download telerik ajax suite (demo) as those controls are referenced in the project. You don't need to modify the functionality (except for the supersignature but that is so specific that could be a different bid/project. Need to be able to communicate in English though I'm learning Spanish.
