Convert VBA code to javascript

I have a VBA application that I need converted to run in javascript and HTML5. The application accesses a MYSQL database to populate drop-down controls. The successful bidder will be experienced in javascript, HTML5 and Visual Basic (Excel). The code to be developed must be thoroughly documented at a top level and with in-line comments. The following is a high level description of the application. A more complete specification will be provided to qualified bidders. 1. Select a document from a list obtained through a SQL query (provided) 2. Document image is visible. Provide controls to: a. Rotate page to its readable orientation b. Flip the page so that the logical first page is showing c. Zoom into a portion of the image 3. Perform a SQL query (to be provided) that will populate a drop-down with valid codes. Select a code in the drop-down that is visible on image. 4. Using the Document ID (Step 1) and the Code (Step 3), perform a SQL query (provided) on the database to obtain a two-level list of data items that corresponds to data items that are visible on the image. 5. For each top-level item in the list, format the second-level items in a check-box format. User checks boxes based on what is shown in the image. 6. Iterate through the top-level items. When the top-level data items appear on the second side, flip the image and continue. Information will be provided in the SQL query indicating when to flip the page. 7. Save the results in a transaction file (format to be provided) that will be posted to the database. Provide high-level documentation in block diagram format and clearly written in-line comments that will allow another programmer to maintain and enhance the code.
