Why not begin by talking with tokay breeders? The folks on the Tokay forum might be able to steer you in the right direction since the two species are similar. I only had success with a random egg hatching in an enclosure, so all I did was standard husbandry. Actually I didn't even know about the egg until I saw a baby gecko. As you see in my above post, turned out to be a nice looking golden.

Best of luck!
