NH-Parenting time and family court help!

My boyfriend has court coming up in October and can’t afford a lawyer. Is there anyone in NH that knows of low income lawyers for family court? He has talked to LARC and has talked to someone over the phone but it really didn’t help him in any way. He just wants more time with his son and his EX has a lawyer. She wants more money, he just wants more time with his son. (Currently he has him every other Saturday and Sunday from 10am-5pm with 2 of those hours each day being travel time because she won’t help with transportation...so we travel 8 hours every other weekend just to see him. He has never been able to do an over night since they broke up over 3 years ago only because she doesn’t want him to) Not sure what to do because all the lawyers he’s called want at least a $3,000.00 retainer and charge $200.00 to $300.00 an hour. He’s been out of work for over a year on workers comp due to tearing his ACL at work and needing 2 knee surgeries in less than a year. He was told that he can reduce his child support while out of work because he’s only getting 60% of his gross income while out of work but didn’t because he didn’t want to take money away from his son but she doesn’t care about that and that we’re broke but she’s still getting her money. He doesn’t know what to do and is afraid he’s not going to get anymore time with his son. Anyone else gone through this and know of someone that might be willing to help?
