That board appears to be in fairly good shape, a lot better than I was expecting :-)
Assuming the board mostly all works and there's no problems with the audio stage (which often have
capacitor problems), then you should be able to do it yourself. Instructions
here.
Still, if you want me to do it, I'd estimate around AU$80 for parts, labour and complete board test. Return freight for motherboard extra.
If you can put up with the weird layout, I can also make an A4000 compatible keyboard from a standard PC PS/2 keyboard.
That would be roughly AU$25 for parts and labour, not including the keyboard.
Email me for any more details.
