Hi Morgan, With more over 5+ years of expertise experience (including integrating payment), I did integrating payment system on serveral websites before, exactly for last 3 years. Now after reading your job suggestion, I am so willing to do your job now.
Telling about payment system, with paypal API or Stripe, when user buy sth on your site, your site guide user to paypal link so user can do transfer money from his account to restaurant account. after pay, it redirect to your site again. That all happens using paypal API. now clear? If you have any questions about how to deploy payment system on your site, please have a contact with me. by the way, I want to work with you now and I can accomplish your project within 4 days if it's acceptable to you.
I will wait for your reply. thanks for watching me out.
Regards.
Bozo.
