Hi There!

The battery in my HDX seems to be in a fairly poor state, lasting an hour after a full charge. I contacted Amazon but they don't "repair" them. The prices for a replacement weren't really attractive to me right now. 

I found a guide for replacing the battery, and a battery kit, but honestly I am not very patient with fiddly tasks. Does anyone here know a good repairer, not too expensive, where if I provided the parts, they would replace the battery for me? I am in Auckland?

It's a secondary device for my kids to use, so cost is a factor.
