In reply to DizzyVizion:
Start easy and build over the long term.
Fingers are really easy to damage, take an age to fix and only improve slowly because tendons and connective tissue is slow to adapt.
You can put on strength way faster than your joints and tendons can adapt (which is dangerous to the fingers) so go for a balanced approach: easy build fingers and all around strength and flexibility.
Don't forget the shoulders are often a weak link and are often overlooked so concentrating on the correct form when hanging and doing shoulder exercises is as important as the hang itself.
You can make hangboards (and other training gear) from bits of scrap wood - they are perfectly functional but less ascetically pleasing that bought ones. A pulley and some weights (or bricks) is useful for starting with to reduce the load on your fingers.
