Wheel Help - Replace Spoke or Rebuild

Hi All
Looking for some quick rear wheel advice/opinions.
Hope Pro (3 I think) Hub with Ambrosio Excellence Rim - 32 Hole with Sapim spokes. I Snapped a spoke at 2000 odd miles on the non drive side, had it replaced with no further problems apart from it went very slightly out of true. Got the LBS to true it a few weeks ago. Went to ride the bike this evening on the Turbo but couldn't - the wheel was majorly out of true and jamming against the brakes - hopped of to have a look and saw the reason, another broken spoke. The wheel had done 1500 miles since the last one broke.
Both have broken non drive side at the J bend where it enters the hub. Should I be looking at just replacing the 1 spoke again or is there another underlying reason why they keep breaking and is a total rebuild the best plan ?
I need the wheels to be reliable for commuting in the summer months. When the first one snapped it was still rideable without even opening the brake quick release, but even that would not have worked this time it was that much out of true. At least it was only an excuse not to do a turbo session tonight !
Cheers
Rich

I read around a lot when it happended and it seemed to be that repairing just one spoke is very tricky and if more than one goes it's best to rebuild to ensure even tension etc
If you fail to find someone local, PM me
He also advises the use of washers at the spoke head if there is any detectable play between the spoke and the spoke hole in the hub flange. You didn't mention which Sapim spokes - less than 2mm at the head prob needs washers.
So, check the drive side tension is high enough - in the order of 1000N or above. This dictates the maximum tension you achieve on the NDS due to dishing. And check if there’s any play at the spoke hole, if in doubt use washers.

Indeed, however no builder I know, except myself, actually uses the brass washers... they do really help, I have yet to have a spoke failure on a wheel I built
The shop that trued the wheel a few weeks ago and replaced the first broken spoke is not the same shop that built the wheels as it was near work which was ideal as they fixed the spoke so I could ride home.
I could either entrust them to rebuild the wheel, go to the place that built it originally (20 miles away) and get them to redo it or try and find somewhere else local to do it.
Was the initial build bad for the wheel to have broken a spoke in the first place ?
If the wheel was poorly built in the first place (seems likely unless you've been abusing them a whole lot) I wouldn't be surprised to find several spokes are fatigued and just replacing the one that breaks won't fix it for long. Alternatively the shop that replaced the spoke didn't check the tensions and gave you back a wheel that was prone to breaking (my money is on the original build).
Picture of said wheel.
I weigh 81-82 Kg depending on the time of the week. Just used on the road and my turbo. No abuse as far as I know, do my best to avoid potholes etc !
