hello there,
I can fix the issue you are getting in entering the card details at checkout time. I am a Professional Freelancer with experience of more than 6+ years with specializing in Web-Development & Designing (Wordpress, Woocommerce, eCommerce, PHP, .Net, HTML5, CSS3, Speed Optimization, and SEO ).
I have done this type of work before so I can do it.
Now, I am placing a placeholder bid as the amount field is compulsory to submit this bid.
Thanks & Regards
