Re-design website, link stripe account

I had a website designed earlier this year, but the site needs to be better designed with a logo, better color scheme (more beautiful) etc.

I released funds before the job was complete and The web-designer didn't finish this project.
My website is thaivolunteers.com

1. I need to set up a payment system (link my stripe account)
2. WhatsApp contact (chat with us now)
3. Chat box to get contact email and phone number of potential clients.
4. Attach SSL certificate

Once all of this is complete I will start a Google ad campaign. So if you can also do Google ads and SEO there is a potential for ongoing work.

Please let me know what you can offer and I will choose the best freelancer for this job.

Thanks in advance.
Peter
