I don't know very much about pharma, but I had a professor who worked for a biotech company. She said that if you have a start-up company that makes a product that is worthwhile that could potentially threaten big companies, big biotech companies will try to buy you out. In most cases, these startups are looking to be bought out simply because they can quickly turn a huge profit just a couple of years into business. Also, they may not even have a fully working product when they get bought out.
Anyway, from what it sounds like, you're more idealistic than realistic. You're focused on the end goal and not the actual product. You'll likely never succeed because it takes hundreds of millions of dollars to get a drug onto market, assuming it passes clinical trials which assume it passes lab trials. But...
If you're like me, I'd do all of the testing myself if possible. I like to get my hands dirty with rat sweat, tears, and blood. (Rats don't sweat, btw.) But really, I'd bypass animal testing and go straight to human trial. Me.
