Hi There,
I infer the following tasks to be done on your website :
# You need to integrate paypal as payment gateway to your website.
# There will be a PAY NOW button, when user clicks on this button it will ask them to fill the id or link to their facebook or instagram profile.
# There will be a verification of user account.
# Then there will be a checkout page where they will have to pay through paypal. An email will be sent to user containing the info about product and placed order.
# Then an email will be sent to the outsourcer to deliver the item.
If this is the only requirement , lets freeze it or feel free to discuss if there is anything else you require in your website.
I have lot of experience working with wordpress, Wordpress development tasks, paypal integration,Installation, Installing Themes, Finding / Installing Plugins, Creating Plugins / Widgets etc.
I look forward to speak with you and keen to start this project.
Look forward to hear from you soon.
Regards.
Amrita.
