Implement integration with CYAN for the site on 1C-Bitrix

Good afternoon, there is a ready-made site on CMS 1C-Bitrix it is necessary to implement integration with CYAN.
It is required when adding new real estate to implement their automatic placement on the CYAN website. Also in the future it is planned to integrate with other aggregators (DomClick, Avito, etc.).
I put a random budget, in the response indicate the desired price.
