Add-on Simple Forum Prefix Reorder


I am looking for a way to display threads with a certain prefix before other threads in a forum regardless of any sorting orders. Preferably they should be sorted by date created.

It should be possible to add this to multiple, specific forums of my choosing and not all of them.

If you are able to do this, please let me know a timeframe and price. Please note I have a limited budget.

Many thanks,
