Make an online store on a paid WordPress template

Good afternoon! There is a paid template for WordPress with Envato. You need to set up an online store based on this template with the following functionality:

1. WooCommerce and connection of the online cashier. You need to add / edit / delete products and the possibility of online payment. The bank providing acquiring is still being specified

2. Adding/Editing/Deleting Blog Articles

3. Integration with JivoSite for online communication with the consultant

I will send a link to the template to the selected performer, please indicate the cost and timing of this development when responding. A sample plug will do
