Hi

Ok, the SN74LVC1G125 is 35 cents each at Mouser if you buy at least 10 pieces. That's going to be $3.50. LM78L05 is 26.5 cents if you buy 10 pcs. You will need some bypass caps and resistors, I'd assume you already have them. 

Say you want 10 channels, that's 11 logic id's. At one IC per output that's almost $4 plus the 27 cent regulator. Still under $5 for all the parts. It's roughly $10 if you double up on all the output channels. 

Do a quickie PCB from any of the usual outfits for $10 or so on a small run / one day turn basis. 

Total cost without connectors or case < $20 in very small quantities.
