AJAX website component using ruby on rails (ror)

Dear all, I'm in need of a new web 2.0 website component. The component has to be built from the ground up using Ruby On Rails (latest version), CSS, XHTML, Javascript/Ajax. No flash nor java should be used. For easier development the component should be implemented as a new simple project, we'll do the integration into our existing project ourself. Functionality (please see screenshot too): Imagine a page which has an abitrary number of tables, each with only one column and >= 0 rows. The rows should be stored/read from a mysql database. When you move over a table row, the row should be greyed and a small toolbar should be displayed. The toolbar allows the user to delete the row, add a new row above/below or move the row up/down. When the user clicks on the row, the content of the row should be editable using a wysiwyg html editor (like tinymce). The "tables" must not be done as html <table>s (better as divs), the name "table" has been used for illustration purposes only. Essential features: - standards compliant (w3c validated) - professional look and feel (see screenshot) - clean separation of code and design/templates - Ruby >= 1.9.1, Rails >= 2.3.3, Mysql >= 5.1 should be used (best performance) The source code must be of good quality: - well structured - well documented (only english) - all classes, modules, variables, methods should have meaningfull names The development should start immedately, the timeframe for this project is about 1-2 days. Communication should be really good and done using email, icq and/or msn. The development should be done using an environment I have access to, so that I can always check the current state of the project. I'm looking forward to your reply asap.
