WordPress E-commerce Site Customization

I'm looking for an experienced developer who can help customize my WordPress e-commerce theme for a rental business. The site is hosted on Hostinger and is set up on a rental e-commerce theme. The primary products for rent and purchase are toys.

Key tasks include:
- Enhancing existing cart and account management features
- Creating templates for adding inventory
- Developing a subscription-based feature where users can opt for certain subscriptions and choose specific products associated with those subscriptions
- Allowing users the option to purchase products, in addition to renting them
- Implementing a theme backup and restore mechanism
- Assessing the need for extra plugins (like for subscription) and utilizing free versions where possible

Currently, WooCommerce and WooPayments are installed. I am open to other plugin recommendations. The base setup has all required plugins; I need someone to integrate these and apply the concepts mentioned above.

Ideal freelancers will have:
- Extensive experience with WordPress and WooCommerce
- A strong understanding of e-commerce and subscription-based models
- Ability to create and customize templates
- Knowledge of plugin integration and setup
- Experience with website backup and restoration procedures.
