Dreaming & Scared

So, can I do this?  Am I just dreaming big???  All I've ever done is random quilting.  Can I do a pantograph?  When they called back to verify my order, I added the laser light and rear handles.  I just ordered a couple of pantograph's.  Now, I'm scared!  I know we can afford it with Steve working now and I only have a year of payments with no interest.
Will I get good enough to do other's quilts?  One of my good friends (that took my Shitzu, Tipsy, for a companion) asked me if I quilted for other people, I told her she could look at what I do and I'll quilt for her if she wants me too.  Hopefully all the cones of machine quilting thread I bought will work on the new machine.  Elvira is/was very picky on what thread she uses.
So far, I've only quilted for my friends/students.  They are very happy with what I do.  I do a full size quilt for $60, a twin for $40, baby quilt for $25.  I'm cheap, I'm not perfect, but do I want to be?  Yes, I'm scared.  I tried a bit to follow lines I put on with my stencils and I sucked at it.  But... my machine didn't slow down when I did, nor did the stitches stay regular.  The new Tin Lizzie Apprentice has stitch regulation, needle up/down, and I think I'll love her, but yes, I'm still scared!!!
