I bond between 2 and 3 pairs of rabbits a week for ARC (100 - 150 pairs of rabbits a year) and I will only use the quick method of bonding as I find it far less stressfull for rabbits than the slow method where they are introduced for a small amount of time then separated.
I would certainly recommend using this guide which Cheryl wrote a few years ago

I do not advocate pairing up unneutered rabbits, due to hormonal issues which can result in a bond failing if the old hormones makes her tempremental at times. If you must bond an unneutered female I would suggest doing it prior to the hormones kicking in as this is easier. If fighting starts as the rabbits get older it is essential this is done earlier rather than later ... also take both rabbits to the vets when this is done unless you want to risk having to rebond them.
The key points for me are:
Neutral territory is a must
Keep all other rabbits out of sight and smell from the ones you are bonding.
If handling other rabbits change clothes and wash before handling a pair you are bonding as other rabbit smells can upset your bonding rabbits.
A confinded area so that they have to meet each other and start bonding
A confinded area so that it is easier to split them if they need to be temporarily separated rather than have to chase them around a room whcih increases the chance of injury to you and the buns.
Do not interfere with them unless they are locked on to each other.
Only split them if you need to for the count of 10, then release them back together.
The area you use to start bonding them should be maintained for at least 48 hours to allow them to get used to each other without then having to restart and find out who is the boss in their new territory.
Ensure that you have at least 48 hours where you can supervise them as required as opposed to having to split them after a few hours as you have to go out.
If you expland the territory and they start fighting, restrict the territory again.
Ensure that all areas are either neutral or have been thoroughly cleaned before you allow them access to this new area.
