Update and Questions

So the terrain showcase is going to have to wait for two reasons. One the spray adhesive can I got was a dud, so I cant finish flocking the trees. And two I have just gotten a commission from a friend to paint his space wolves reivers Kill Team. And on that note I have some questions to ask that I would very much appreciate advice on.

How Much is Too Much or Too Little?

So he is going to pay me for the work, but I am not sure how much to charge him. So here are some details of the commission.

He bought 3 of the paints needed for the blue armor, and anything else I need I will use of my paints. Also I will be doing all of the assembly and priming of the models as well.

What I am Thinking

There are five (5) models and I am thinking of charging him $5-$10 per model ($10 per model roughly equates to $2.50 an hour). We have not discussed prices at all he just said he would pay. So am I high balling or low balling the price? I dont want to charge him more than the models cost to paint them, but I also dont want to get ripped off on the labor/pay ratio. For anyone who has taken or paid for commission I would be very grateful for you advice.
