Migrate .swf from Flash CS4 to Flex 2 or newer version - repost

I need someone to get my project from Flex 2 and Flash CS4 and migrate the embed .swf from Flash CS4 to only use Flex 2 or a newer version of Flex, the important is all use only Flex. Because compile the project using a embed .swf compiled from a .fla Flash CS4 file, when you debug is too slow to develop, you need to login and test to found a bug of syntax and it takes 4~7 minutes each debug. Now if it have all done in Flex, only when click to compile the syntax error or any error will return in seconds, this will speed up the development alot. The project is a card game developed from a example of Smartfox Pro 1.6.6, that use Flex 2 and Flash CS4. It is a very simple and small game for two players, a person with experience can done this project in one day or two. I will choose the lower offer.
