I have all my divorce paperwork and it's signed by her. I need it filed and my signature notorized.

There is no question there.  You can find a notary anywhere (your bank, any lawyer's office, etc.).  Instructions on how to file papers are on the self-help center website.  If you require additional assistance, there are services, such as "Document Preparation Service," run out of this law office, which will assist you in getting papers into proper form and getting them filed, at a minimal cost.
