Answers to your questions about the Netherlands

A budget has three parts. There are the government fees the IND charges per application, including for family members; there is our fee for preparing and filing the case; and, where we act as the employer through payrolling, there is a monthly amount tied to the salary that has to meet the required threshold. Document legalisation and translations come on top and depend on your country. You get the full breakdown in writing before anything starts, so the monthly commitment is clear and not just the first invoice.
