Develop Flash site further (AS3) approx 20hrs

I have a three language flash site with xml-file to edit content. I need mainly small fixes to it: such as text updates, moving some elements to another place and removing images. All of these fixes are already made in one language version but have to be transferred to two other languages. I do not have the very latest .fla file so some features have to be re-done or convert from swf to fla. I can post the lint to site by PM if you need to check it. The used technique is actionscript 3 and i would estimate that the updates (without upload image -function) is about 20hours for experienced developer. These updates must be made during this week. The site is continously under development so I will need help for coming years as well (approx 5 hours per month).
