Minor Application Adjustments

I have application already designed and ready to go, I just need some very minor adjustments. Time estimate on how much it should take no more then 10 hours. I cannot provide the application itself at this time, but when I select a coder you will be able to see it. Here is what needs to happen: 1. There is background image, it is purple color - we need to change it to skyblue. 2. There? are couple of? reports which I need to print, text prints fine, however graphics do not print. 3. On one or two reports when I export to XLS and print the color of the letters prints light black, but not dark black, I need to make sure that the color stays dark black. 4. there is 3 or 4 fields on one of the forms which sometimes saves and sometimes does not. There is obviously logic that needs to be corrected so that it saved. 5. Application already exports a report to PDF, and it saves to a specific location on the computer, I would like for the application to envoke save as dialog box so that you can choose where to save the file, and the file name. Very simple changes, this is written in C#? .NET with Access as backend DB. This should not take more than 10 hours, my estimate is 5 hours, but please bid accordingly. This application will need more work done down the line, so this would be first step to get in and get familiar with the project. I also have several other applications being developed right now, so if you do good and professional work and you are price right I will use you again and again.
