Whoops, bad, ignore.
Anyway, what I was going to write was that I've painted dozens of these
ships, as well as scratchbuilding a nd painting a lot of others, and
they vary a lot in regards in complexity of painting them correctly,
with the NCC-1701D being hands-down the most difficult, due the vast
number of space lifeboat hatches on it.
That takes around thirty hours of very careful painting to get right.
I'd suggest learning to paint them yourself, as otherwise even at low
price-per-hour it's going to be very steep in regards to final cost for
what you want.
You could easily end up with a STNG Enterprise that costs you over
$500.00 if painted right, and frankly, that's a lot more than it would
cost to learn how to paint it right on your own, even if it meant buying
one or more to practice on before you did a finished one.
And if you can handle painting that ship right, you can handle painting
_any_ ship in the ST universe...easily.
