I live in the UK, googled wetsuit repair. There were a few places nearby and just dropped it off. Pretty cheap.

^^^^This.

I've even had a luggage repair place do it.

Call a nearby swim/paddle shop or tri group. There is usually someone doing repairs like this. If in US, REI or other chain often has a person they refer to. I once used a shoe repair shop-piece of cake for them and turned out better than my previous DIY.
