DU (or is that Depleted Uranium?)
As you may be aware, I will build up amps and power supplies, but you still need someone to put it in an enclosure and wire up the bits and pieces, like the transformers, the IEC main plug, the mains switch, the amps to power supply, the speaker wires and binding posts. This is not difficult work, you could easily learn yourself, but yes, great idea, you need someone to at least look over your shoulder.
And, I'd echo Malcolm's question - Where Do You Live?
Cheers,
