"If that much money would be paid in a period of year, the orphanage management would also stabilize. On the contrary, Bob would be able to reconstruct it or add more buildings as much as he pleased. He wouldn't have to worry about the debt anymore."
I found this sentence in a book I'm reading.
EDIT: I forgot to say that it's Bob (the orphanage manager) the one who is being paid, so "on the contrary" here is used to say that now that Bob has money, not only he can stabilize the situation of the orphanage that has been poor until now, but he can even restructure it or add more building to it.

"Otherwise Bob would be able to..."
You probably also want to add "a" before "year" so it reads:
"If that much money would be paid in a period of a year..."
