Does anyone know what support is available for autistic people trying to relocate?

Hi I've been trying to move for over a year now. My Girlfriend lives about 70 miles away but her local council won't entertain peopel applying for social housing who have not already lived in the area for at least 5 years which prevents that course of action and private landlords have no interest in renting to benefit claimants. I did managed to contact one housing group who were supposed to cater for autistic people but since I don't have a social worker they were unable to help. 

It's really starting to impact my mental wellbeing not being able to see my girlfriend particularly with all the lockdown stuff and I'm feeling trapped. Does anyone know of any systems which may be in place to help me move?
