Deadlines for the completion of the work must be negotiated individually. Usually, if we are talking about a simple site, the terms time will be from 1 to 3 days. If the site is more complex, then the terms can be from one week or more.
If the site was made on Wix, then you will get the site on your Wix account, if you do not have an account, we will create it for you. If the site was made on WordPress, then you will receive a username and password from the hosting and a username and password from your site.
