I used employee leasing. It is many times more convenient than running a recruitment campaign. I applied for an Employer of Record in Russia link here to this company. The selection of employees and all the paperwork fades into the background, or, to be more precise, this company does everything for you. After all, they do the recruitment and all paperwork, and the calculation of pension payments, and similar troubles with taxes. They can also select employees carefully according to your criteria.
