Nadia specialises in Cinematic YCHs, and I commissioned my first from her in February. She has a quick turnaround, is very friendly, and produces high quality art for a good price - not cheap, but still affordable. Most of her YCH's are auctions though so the price can get high if there's competition.
Nadia also occasionally offers other special deals for a limited time or limited slots. I commissioned a series of character portraits from her through February and March, and after the first few she allowed me to claim several slots ahead and pay one at a time. We've now repeated this arrangement for her special on Character Reference Sheets.
I am incredibly happy with every piece I get from her and there is never long between updates. After the initial information is sent I will usually receive a coloured sketch back for review within a few days and she will start lining quickly. She is also very good about making changes/fixes for things like clothing colours and skin tones.
