Hebrew to English Bus/Financial Law: Contract(s) Local Government

From a leasing agreement;

The Lessee, and he alone, shall be responsible for receiving the permits and licenses required by law for managing his business in the Rented Object and for complying with them during the entire rental period, all on his account and under his responsibility.

The Lessee declares that he is בקיא ומצוי
בעסק that he intends managing in the Rented Object and with the entire subject of the required licensing and permits ....

"conversant with" seems okay as its used twice. "to be found at" doesn't jibe.
