I just wanted to offer some kind words. I know you're getting a lot of flack for this post, and I want to let you know that I was in a similar boat when I was your age.
My parents let me get two rabbits when I was 12, specifically so I could breed them, and I was able to sell the babies through 4-H functions (also note that they were NOT purebreds, and I live in a very rural area, so not many people). I actually got a 3rd doe as a stray that summer, as well. Before long, I actually had about 9 crossbred rabbits, 4 of which were second generation rabbits. When I got into high school, I was able to buy my first purebred rabbit (a mini rex) and joined the ARBA. I got my first purebred breeding pair (Flemish) when I was 16. My activities during high school were band (marching practice before school), 4-H and FFA, so like you, rabbits were my "thing".
Because of how remote I was, I only managed to make it to a couple shows a year, and didn't ever earn any legs (Flemish were really rare around here, then). I had fun, but I did have a hard time finding homes for the Flemish kits because I wasn't willing to sell them for pets (and a lot of people who wanted pets didn't want to have to BUILD the cages, which they would've had to do since the only cages sold around here are barely suitable for medium-sized breeds).
I kept track of all my income and expenses, and it was hard to turn a profit, even back then when feed cost half as much as it does now. I was lucky enough to sell almost all of my kits, and had a place for any rabbits I didn't sell. I think I only managed a profit because I entered market trios into the junior auction every fair.
When I went off to college, I had to get rid of it ALL. My mom was actually afraid of the rabbits, my dad had his own hobbies, and my little sister wasn't responsible enough (not to mention having all her time taken up by sports). I was lucky to be able to get some of my friends from 4-H to take cages and crossbreds, but my Flemishes got sold at a huge loss. I tried to convince the college I would be attending to let me bring the rabbits (they have an old rabbit barn, that to my knowledge wasn't even being used anymore because of lack of research funding), but I never got a response.
I was away from rabbits for about 6 years (except for a couple elderly pet rabbits), and am just now getting back into breeding, but it's taking all of my excess income from a decent salary to start back up (that's for 25 total holes divided between 3 breeds).
I applaud your enthusiasm and wish you the best of luck in your endeavor, but I advise you to keep your numbers limited, and only breed for dates that you expect to be able sell on (ready for adoption at a certain show or other event--I bred for fair and Easter with my crossbreds). Your holland lops will probably sell best as pets (the competition for that breed is HUGE, so without a show reputation, you won't find many breeders who want to buy, unless your pedigrees have some of the top names on them). I'm not very familiar with the mini satin and himalayan markets, but I think you'll find that trying to sell them will be difficult.
Have fun with the rabbits you have, enter them in ARBA shows, and look for mates there--watch for who's winning to get yourself the best lines possible. I also check the national breed club show results to see who has the best rabbit of the varieties you want to raise (check the national breed show, and ARBA Nationals results, for the past 2-4 years), and try to get rabbits that have those names on the pedigree.
