Its a risk reward type of scenario.
You could buy a used motherboard, hope it works and fits, and do the swap yourself. If it works you saved a bunch. If it doesn't your back to square one, minus all the time it took.
Or pay a tech to do it. It will be working in the end, but at what cost? The labor won't be cheap and its no quick job. It takes time to do it right. Especially if your moving the CPU from one board to the other. There is cleanup of the old thermal past/pad and new stuff to apply.
