I think everyone can learn how to draw. One simply needs imagination and hard-will to try to pass challenges. Talent is simply having a skill much sooner than others. Say someone has a talent for drawing: They see much quicker and learn much quicker what makes a drawing 'good' or 'better'.
It does not mean people who don't have this talent can't learn to draw.
As Michen pointed out, we have a whole Art board dedicated to... well Art

If you want someone to draw something for you, check out the Requests board. Or you can also check out the Art for sale/trade/free to see if anyone is offering art.
Need help with drawing? Check out the current Artistic Stuff topics to see if there is anything helpful there

But drawing can be fun and really rewarding if you stick to it. (Then again I have come across a few people who get 0% enjoyment from drawing

)
