I need a web developer

Just to add a calendar to book appointments with my schedule and payment method which I had as PayPal & stripe but the payments methods disappeared. I don’t know if I have to pay to get them installed again, but I hope not as I already paid.

I had this on previous website but it somehow got deleted

I used developers that were very difficult to work with & I did most of the work. I only needed them for the technical booking and calendar and payment area which they couldn’t even do that right -they charged me a lot & could not even complete the task right.

I cannot afford to pay very much as I am on a tight budget. I am retired person who just wants to try to help people..
