Pro bono? Nearly impossible these days, but you could try calling the Alameda County (510-302-2222)or Contra Costa County (925-686-6900) bar associations for suggestions. There's also Bay Area Legal Aid (510-663-4744 or 925-233-9954), but they are pretty tapped out right now and generally only offer services to people who are in dire financial need.
In terms of decreased cost, you may have a better shot, but it would require you to potentially consult with numerous attorneys to see who is willing to work at a discounted rate. The two county bar associations have a "moderate means" panel of attorneys who offer services at discount rates, so you might try asking specifically for that.
