It isn't that you're too young per se, it is that you don't have much credible experience.  VP of the family jewelry business is nice, but that's your family business and even if you're doing as much work as anyone else would be doing, it is hard for an employer to take that entirely seriously.  They all know that you wouldn't be in that job, at that level, based on any actual experience you have, nor is it based on what you studied in college.  In short, no one else would hire you into that job in the first place, so it is hard for them to make the leap that you're putting as much in or getting as much out of that position as you might think.

And one year, part-time with disabled people isn't going to help you break into the business world either.  I myself did that work for 10 years (residential, recreational and educational) so I know what it involves, but most people don't know and frankly don't care.  They see it (if they think about it at all) as glorified baby sitting.  Actually, many people see child care as more prestigious. 

While you do have good education credentials, you don't really have the experience to back them up yet.  It may have been a bit too soon to get a Masters degree.  That won't really pay off for you until you've got 5-10 years of experience in your field to put with it.  Getting a second Masters degree at this time would probably be a HUGE mistake.  It is going to make your resume scream "professional student" and isn't going to help your experience issue one bit.  You'll finish school two years from now with the same lack of experience and more debt.

So the challenge for you is to package what you've done in a way that allows an employer to look at you and see someone who is hard working, credible, reliable, responsible, wiling to learn and eager to move up and grow with them.  You need to look at jobs that are reasonable.  If you want to go into the business sector, then you need to look at entry-level management jobs in the types of companies and departments you want to be in.  You're not going to get into a VP (or even AVP job) straight off the bat.  You're going to have to start with jobs like Admin Assistant, Customer Service Rep, Assistant Account Rep, etc.  That you do have some work experience is going to help (definitely puts you ahead of someone with none) but don't think that you're going to be greatly rewarded for part-time and family business.

I also find it interesting that you haven't said what exactly you want to do.  "I'm willing to do anything" is great but an employer is looking for you to have a little bit of focus.  "I'm willing to do anything that will get me to X" is what we want to hear.  If you need help figuring out what you should be doing, see the career center at your alma mater.  They can do testing to see where your skills, interests and abilities lie and suggest a number of career paths and related fields you may not have considered.  When you say Director of a non-profit or for profit, you don't say what kind or why.  The career center can help you with this.  They can help you focus your resume, practice interviews with you and supply you with job postings and internship opportunities.

The other option is to continue to work and grow in your family business.  If that's working for you and your family, you don't HAVE to go work for someone else.

I found I had the same problem when I graduated but with less education than you.  I graudated with a psychology degree from an accredited university and wanted to go into the HR field.  Every place I applied to was less interested in the education and more interested in the experience and I found it nearly impossible to get my foot in the door.  In the end I went through a temp. agency and took a job as an HR Assistant.  The temp. job turned permanent and now I have the experience I need so I would not suggest any more education but rather accept a lower job and work your way up.
