Familiars have fairly standardized rules for this stuff:
1. Wait one week in game.
2. spend 200 gp per level (just the bloodrager levels, plus levels from any other class with a familiar you might have that stack).
3. do an 8 hour ritual.
Yes. It is a lot of trouble. That is why most people are afraid of using their familiars as anything other than a stat booster. Compared to animal companions (which you can replace for free after a 24 hour ritual), they are often too valuable to risk in direct combat.
