Which cms, service or template to choose?

Question

CMS

Hello, gurus and sorcerers of the entire Internet.

Need cms or service for certain requirements:
Intellectual product. Or rather, not even a product, but a service that is sold in a large number of template options.
1. Option selection menu with checkboxes so that when the checkbox is checked in the selection menu, positions that do not satisfy the search disappear. A striking example is the online store Yulmart.
2. The product field itself should display an application form when clicking on a product.
3. Notifications about new applications by e-mail or integration with Bitrix24 - it would be generally chocolate.
4. A paid solution is possible, but according to the rental model or free.
5. Do not offer to code. Long and gemoroyno because the service is needed for a short time.

Thank you all in advance. With the upcoming NG.
