You're laurelindebear? I wasn't sure! 
Yep that's me! Regular 'Laurelinde' gets taken pretty fast so I have to improvise a lot of places. (I tried *so* many Twitter handles, you wouldn't believe it.)
Sorry for an OT question, but I've been thinking about commissioning some work and I have no idea where to start. Have a lot of you guys commissioned work before? I found an artist I really love and was checking out prices and I almost had a heart attack when I saw how expensive it is....like $1,000+ for two characters from the waist up.
After I saw the price I was like NOPE. In general, is that a normal price? I understand that's how artists make their livelihood, but that's a lot of money to invest.
I've commissioned a few things over the years and prices generally vary dramatically based on a number of things. Size/detail is the obvious one; larger works, works with more characters in them, works with detailed or complex backgrounds all take a lot more time I think, so they cost more. Bust portraits or waist-up shots with only one or two characters generally cost a lot less. Medium affects it too, although that can go either way IME - some artists charge more for digital work/color and some charge more for physical works on paper or card. I would imagine some of it just boils down to what they do more or less of and therefore how many hours of labor go into a piece.
Beyond that I think prices tend to reflect what artists feel is an accurate reflection of their skills, and then probably how much they rely on commissions as a source of income. Artists who spend a lot of time on concept contracts will probably charge more, because they have a lot of interest and less free time than someone who just draws as a hobby and/or has another regular gig of some kind.
I have commissioned Aimo for sketchcards a few times (thinking of commissioning her again for a Cullen/Quizzy card, if I can decide on a pose!) and her prices are very, very reasonable considering her level of skill/experience, to me (they run $25 per card.) The woman who drew the picture linked above also only charged $30 for that and the actual image file she sent me is *massive* - so I can easily use that picture as PC wallpaper or what have you. There's no background or anything, but it's fine for my purposes! I would quite happily recommend both of them for commissions, my experiences with them were very positive and professional. 
If you have a look round tumblr and Deviantart you should be able to find some people whose work appeals to you and hopefully are in your price range. The really top of the line artists, yeah, you'd need to be loaded! I look at some of the custom plush people make (where materials are a lot more costly as well) and just dream, because there's no way I can justify spending $200-$500 on a fuzzy pony or something (sadly. I'm pretty sure me being an adult was an egregious error on someone's part.)
