140562 Modify Script PHP Flash

Hi i need someone to modify a existing Digg clone script. [login to view URL] I will need someone to make a flash search function. I want people to be able to search old news. eg I want to know what happened between July 2001 and October 2oo1 instead of manually typing in 2 dates I will use a FLASH TIme graph. I will CLICK and DRAG from Date 1 to Date 2. This will give me the time period. LAter i should be able to compare 2 periods, therefore i need to be able to CLICK and DRAG 4 different dates like in pic included. How much to do this.... later there is more work on the project. It is important to make this in flash Please tell me will i need flash server or anything like that? I am willing to buy flash charting software if needed.. something cheap
