As for getting your work framed, you are going to have to spend money in order to make money---when you sell a framed work, you'll want to add the framing cost to the value you want from it.

There are many ways to price artwork.  I work in pastel and in different sizes.  Each size has a different value I wish to profit from (how much I value the size of artwork).  Then I add an estimated materials price (pastels, fixitive, paper, etc..) used in the work.  After I frame it, I include the framing price.  This way the I know I'm not cutting into my profits when paying expenses (materials and framing) on the next piece.  Otherwise, you might spend more money than you are making---that's not a profit---that's a loss.
