I guess I'll give this a shot... I usually draw a lot of male human characters but, I can draw women too (unfortunately, I have few examples and I apologize for that...)
My commission prices (currently running a Emergency Commission sale for cleaned line art at the moment) can be found in my shop here
If you want a flat-colored rough sketch of your group (it's going to be an extra $10USD per character in this case for the 5-10), it will cost $135USD. If you want (cel) shading, it's going to bump it up to $145USD. This is the cheapest option.
For the current discount clean-line art (which will take a long time, and I have about 2-3 clients ahead of you) it's going to cost $150USD for flat colors only, $155USD with (cel) shading. Painterly-style shading will be $10USD.
If you have a due date of when this needs to be done, please tell me!
Thank you for reading this!
Otherwise, good luck in finding an artist that suits your needs!
