Netherland dwarves are a breed prone to many health problems. For all rabbit breeding it is important to use only rabbits that you know the genetic history of several generations back, and for a breed like nethies it is even more important so that you do not produce rabbits with these genetic problems. You will be throwing yourself way into the deep end by starting with nethies.
You will also need a pretty thick skin, as you will undoubtedly at some point have peanuts in your litters, and will have to watch them die.
As has already been said, you would need to think about your purpose in breeding first as that will affect how and if you breed your rabbits. You'll also have to read up on genetics thoroughly and decide what traits and colours you will focus on.
To be perfectly honest with you, if you breed your rabbits they will not have the best life that you can offer. The RSPCA and RWAF welfare guidelines for rabbits state that they should live in bonded pairs, but this isn't possible when breeding rabbits, as you have to keep them separately. It is also recommended to neuter rabbits so that they live happily with others and to prevent females from getting uterine cancer, but of course if you are going to breed them you can't neuter them till they are older. You'll also need a very large garden and a fair bit of cash to build an initial breeding setup that meets welfare guidelines (6ftx2ft hutch attached to a 8ftx4ft run for each rabbit/young litter).
If you have the cash, the time and the space available, by all means you could be a successful breeder, but do make sure you research it thoroughly first and you have everything in place before getting the rabbits, or things can very quickly get out of control. Sadly a lot of breeders don't meet the RSPCA standards of welfare, so it would be a nice change to see a breeder with the proper size hutches and runs and breeding for the good of the rabbits
However, if you think you'd like having just a few rabbits, enjoying getting to know them and keeping them in pairs or groups, it may be better to consider having them as pets. You could even consider fostering litters of rabbits for a rescue if you are keen on having litters around.
