My friend - you are in a world of opinion.
Might I ask you to do two things:
1. Go around to the locals in your area to see what they do and how they do it
2. Talk to your Dad - he does not need to START into this business with you in his condition - taking over the operation is a lot different than STARTING a new one.
Otherwise i would suggest you buy some solid bred cows with calves at side - and NOT until you have a way to pen them and restrain them - infrastructure is far more important than cows - especially when you start out as a newbie.
If you are a hobby operation buy 5 bred pairs and stay there until you know what you are doing.
If you are thinking of buying a couple hundred - well, you have enough money to hire a consultant - did that once myself - they nearly broke me!
Now this should start the 27 questions rolling and the the thirty thousand suggestions - all of which will probably be valid for the area the writer comes from and in turn might do nothing but hurt you in your area.
So think long and hard on this - it is NOT a money maker for a long time - do you really want to spend a pile of cash in your situation?
Might not make a penny after a lot of years and still spend more than you want.
For heavens sake - do not borrow unless you are quite happy to make a payment for a long time - or you need some serious tax deductions - and if you are that well off I sure wouldn't be looking to put my money into cows.
That old bastard down the road that drives the rusted out pick up, lives in a house that needs some repair and wears the coveralls that should have been replaced three years ago is probably me - so you might want to talk to him - because he is still in the biz.
The guy living with flash, the fancy bely buckle and silver hat band is probably talking a good story and wondering if he can hang on until next year.
Personally I would advise you to go real - REAL - slow.
My best
BC
