How can I add an Expiry Date to threads?

[kinggori]

Hi guys,

I run a shopping deals and coupons forum and I'd like to give members the ability to add an expiry date to a coupon (thread) when posting a new thread. When we reach that expiry date the thread then automatically gets moved to an "Expired Coupons" section.

Any idea how I could implement this, where I could get started or if there are any mods out there that could help me implement this?

I'm also willing to pay a programmer to help me implement this.

Thanks
