It appears that you are asking what your options are for enforcement, or in the alternative, to revisit the divorce and alter the separation agreement to award you more of the marital property in lieu of maintenance. For enforcement, you can file a motion requesting your ex be held in contempt for failure to follow the court's order to pay you spousal maintenance. If he is found to be in contempt, the court can impose fines or even jail time. As to revisiting the settlement agreement (the order that divided the property in the divorce), that is governed by C.R.S. 14-10-122. Modifications of property settlements can be extremely complicated. However, it is important to understand that none of these processes require an attorney, so you could proceed pro se, or unrepresented. Setting an assessment with an experience family law attorney can help you review your options and better understand your likelihood of success.
