Experienced Quake 3 Dev for Server-Side Feature

I’m looking for someone experienced with Quake 3 engine (id Tech 3) to implement a small server-side gameplay feature.

Task:
Create a temporary “boost” mechanic:

When a player gets a kill, they receive:
+25% movement speed
lasts 5 seconds
Effect should not stack, but should refresh duration on a new kill
Must be controlled via a CVAR (enable/disable + adjust multiplier + duration)

Requirements:
Implement server-side (game module)
Must persist correctly across respawn / death states
No client-side hacks or shortcuts
Clean integration with existing movement logic (no breaking pmove)

Nice to have:
Optional visual indicator (server-triggered event or flag)

I will provide whichever files you need to edit from the SDK, just let me know which files you need.

**PLEASE ONLY BID IF YOU HAVE EXPERIENCE EDITING THE QUAKE 3 ENGINE!

I'm only looking for someone who has the knowledge to do this correctly, no guess work.

I will be able to tell instantly if you know what you are talking about or just pretending.
