We are 1 of 3 companies bidding on a job that will require illustrations.
Because we are bidding, the details may change, but right now we will probably need:
5 different planets seen from space.
2 cool-looking aliens (please give us a price per alien), and several sci-fi weapons (please give us a price per weapon).
We may just need a few of the aliens and weapons, we may need more, we may just need the planets.
Please show us samples, which we will show the client.
Once we know the scope of work, we will ask for a fixed price, though we can leave the hourly price up.
