Non compete contract for Timeshare sales

I am a licensed Real Estate Agent and was working as a Independant contractor, even tho I was required to go to the store M-F 9-5 , I received a bi weekly "salery" plus commissions.
I signed a non compete clause 4 years ago that states I cant work for a competitor in the timeshare resale business for 2 years or with in a 50 mile radius ( there was no compensation offered). I would literally have to relocate to comply with the contract. I cant go 2 years without a job, trying to raise 3 kids by myself.It is a small business in Palm Springs Calif. I recently resigned my position because they sold the business and decided to open my own home based internet timeshare resale business to stay home with my 3 kids, do you think under these circumstances the non compete would hold up?
