How much are you and your ex willing and able to pay ? What commitment can you two make per year for college? That amount is crucial in determining what is possible.
Run the NPC for the FAFSA only schools and see what they are saying they will give in aid. Be aware that at such schools, any payments for college by the noncustodial parent, actually any payments on behalf or to the student from the NCP will be counted as income on FAFSA a when that year’s income needs to be reported, so the money from that parent either has to be gifted to the OP or lent to the student with appropriate loan documentation.
The PROFILE schools will require both parents’ financials. YMMV as to what sort of financial aid is forthcoming.
