Good running administrative offices near Rotterdam

Two older entrepreneurs ( 57 and 60) are looking for an acquisition candidate. They want to stop working in about 2 years and sell because there is no succession. This is a well computerized office with partly subscription clients. There are significant opportunities in the advisory practice.

Details
Apart from the 2 entrepreneurs, 3 FTEs are still employed. These are very experienced and well-trained people. The office performs all possible administrative and fiscal work including payroll administration. The building is a rental property in a beautiful (sight) location.
