What I would like to know first is how big of an area do you have to raise this many cattle? And where abouts are you located?
Angus over Holstein may be okay if you're not looking for an actual profit off them, and are just interested in doing this for a hobby, not for actual profit. Reason I say this is because the calves may be docked because of the dairy influence they have, but other than that the only worry I have for you is that a) you may not have a big enough land base to work with b) heifers are a royal pain in the arse to start with for a newbie like yourself, and c) are you capable of knowing how to handle, raise and care for a bull?
With only ten heifers, consider AI instead of a bull, especially if you have "limited space" like you mentioned before.
Or better yet, get some beef cows. If you're looking to hit the market with some calves, and want to do it without having to go in the red with feed expenses with having potentially ten Holstein cows to raise and the extra labour to have to milk them out every day (don't forget Holsteins are dairy cows, they make a helluva lot more milk than even one of their calves need, even if they're bred to Angus), beef cows that are medium to small in frame, good feed converters and will raise a good calf without you having to go out of your way to have them milked all the time (calves are the ones only needed to milk them), are your best bet.
So I'd completely scrap the idea of Holstein heifers unless you're planning a small-time dairy operation.
Oh, and get that bull calf castrated ASAP. He's going to turn into a nasty SOB at around 12 months of age, even if he's just being raised for the freezer.
So with all that above, I have some more questions for you:
1) Are your plans with these cattle for just beef and a bit of profit on the side, or are you looking for both milk and beef?
2) Are you willing to spend extra money on extra feed?
3) If you are considering "no" for Q. 2), are you then considering raising these animals on just grass and hay alone with mineral and water at the side?
4) Have you considered the backgrounding route where you can buy young steer calves, graze them on grass for several months to a year then sell them, possibly keeping one back for your freezer?
5) Is a bull the only option you have for your potential breeding herd or do you have access to AI?
6) Are you planning on just breeding the heifers once then selling them, or are you wanting to keep them long-term, keeping them producing a calf once a year?
I know you said your in a bit of a financial clincher now, but from what I've been reading of your post, and what your plans are, I've a feeling that you're going to get into even more trouble with those holstein girls if a) you decide to keep them as cows and b) need to buy feed to keep them. If you are wanting a beef breeding herd (which almost sounds like you do, but correct me if I'm wrong), then do consider the option of purchasing a couple experienced beef cows instead to get your feet wet. Holstein heifers are a bit more pricey than bull calves, and are less cheap than a couple of good beef cows that someone's willing to let go. They're even less cheap in the long run as they grow into cows.
Just some advice to consider, and good luck with your future plans.
