Simple Flash Layer Animation

Hi I am creating a few flash files, and for them I need a small animated explosion. I will need four different sizes of it: 50x50 100x100 150x150 200x200 I would like for it to be sent to me in a .fla file so that I can easily copy the frames in flash and paste them on other files I am using. To give you an example of what I need to do, please go here: [login to view URL] download this file. Towards the end of the video, you will see the guy on the left punch the guy on the right in the face. I would to have the explosion animation occur right after the guy gets punched in the face. If you are willing to do this immediately, send me a link to a .swf so I can see your work, I will hire you immediately and you can also create the different sizes. But it is absolutely imperative that you create this so that I can place the frames on other animations and they will work properly. This means that it must be clear, and if I paste the frames on another file, even though the frames will technically be in a square, it must be created so that you can only see the lines of the animations. Basically, anything inside the square that does not contain part of the explosion must be transparent so you can see everything behind it. Regarding the explosion, I would like fire and a puff of smoke. If you can quickly create this and send me a sample, I'll likely hire you if it looks good. I'll be online within the next three hours so please send me what you can and I'll reply as soon as possible! Thanks, Brian
