Membership Software (Desktop)

Good day, We are looking someone to develop a software to manage members in the desktop. The software will manage members and their quotas payment. We have included some screen shots of a similar software, to summarize the features we would like: - Add and Edit Members. - Manage software editor and admins (for example we will add logins to the software and only admins can delete the members). - Delete members/data, only available to software users with permissions. - Create Groups of Members. - Create new data fields (text boxes, drop-down selections, etc). - Import data (from XML or Excel file). - Save data in a database (SQL Lite or MySQL). - Log when the data was edit/inserted/deleted and by who. - Sync with a MySQL DB (we will provide all details on this) - Export data (XML, Excel, SQL and other we will provide everything with samples). - Automatic backup, every set time the DB will be sent to a remote server. - Simple license system, we will generate a serial key based on a id of the computer. If doesn't match it will not allow to install. For each install we it will be sent an email with several of the computer details. The software should work on Windows XP, Vista and 7 and we would like if you can provide to MacOS as well. We will provide to the selected coder the fields we need, the screens of every part of the software including workflows and samples. When bid please provide me the following: - The time to complete the software, - The programming language you will use to build the software. - If you can provide the software to others platforms like MacOS using Java for example. - Your portfolio. Thank you ## Deliverables Work on: - Windows XP - Windows Vista - Windows 7 - MacOS (optional) Should have a: - MySQL - SQL Lite - Other if suggested by the coder- Programming Language: - I'm open to suggestions here, Visual Basic and C# will be my favourite.
