Congratulations!
Isn't it nice to have an understanding wife, I'm blessed in that way too.
For aftermarket wheels you could do a search for Pegasus, Fujimi, Aoshima and Hoppin' hydros to find out what kind of wheel sets you like and to see which on-line store you'd prefer.
Pegasus has a wheel set called Chrome T's that would suite your Camaro just fine, maybe a bit common but nevertheless a classic combo in modern size.
They look like this and you can find a set for around $8 to $9
Please let us know how your build comes along
