Soloing at 30 is crap and 65 is a rip off! This of course is all based on how well you’re doing. Go to a local airport and start networking. The GA community is very welcoming and there’s always a person(s) who are willing to trade labor for flight hours. I.e. clean the plane, hangar, etc
The best way of doing this in the cheapest manner is to get into the FAR/AIM Part 61 and see what you can combine into training to help eliminate unnecessary hours. An example would be doing your night flights as XC rides, so you can accomplish 2 things at once. A lot of instructors are good at doing this, but there are some out there that are more interested in building hours then your training.
