My time and skills are for hire. I don't have a static price guide. Models are various, some can be done in 10 hours, for others 30 hours is not enough so I set up the price individually. It depends on the level also, but I prefer to paint to the highest level I can achieve.

Generally I require partially advance payment. It depends on the value of the commissions final price. In most cases it is between 20% - 50%. 
If you have any questions feel free to contact me
