Tours travel site develop

I’m looking for a freelancer to develop a tours travel website on a WordPress platform with shopping cart and content management system (CMS) features. The website needs to be well-designed, secure, and SEO friendly. I need the freelancer to provide complete setup and customization of WordPress, including the plugins and themes required. The site will be integrated with a payment gateway and should have secure processing of payments.

1. I have decided the theme
2. I want to be able to post Tours, users can buy and the tour operator will get an email confirming transaction.
3. Tour operator will have a time to accept or decline the transaction
