convert a wheel for gears to a wheel for single speed/fixed.

hi - newbie here, so forgive me for the newbie questions.

I have a velocity fusion rim which I really like, and its currently hooked up to a hub for gears.
I’m guessing I can have the wheel pulled apart and rebuilt with a track hub for single/fixed right?

Question is - is it worth doing this, or will it not be worth the cost and should I just have a wheel built from scratch?

And any suggestions on who could do the work in/around Melbourne? Doesnt need to be a bike shop.

If you just wanna run single speed Google “single speed conversion kit”, if you wanna run fixed buy a new wheel off ebay, if you wanna get ranted at ask about a “surly fixer”.
