Hands-on Help completing 1794a DAC build

I am in search of someone with experience successfully building 1794 based DAC circuits who can complete a 1794 DIY project. Ideally I would like a couple of different transistor based I/V stages so that I can hear difference and choose. I have built the DAC circuit and surrounding components for one channel of dual mono design following the TI spec. I am out of time as an urgent commitment has come up. I would preferably like to work with someone close to Silver Spring MD but open to other options.

If interested you can PM me for more details.
