Simply send the offer to your client for developing the website.
For Example, I will build a 10-page website for you and the cost would be $150. You need to have an active domain and hosting service and provide me with the login details before I start the work. For developing the website I need a Joomla package that would be integrated with your website and you will be the owner of the plugin. You can buy a Joomla package that I will share with you and provide me the login details of Joomla to integrate with your website. So here you charge the client $150 only which is for your time and expertise. Hope it helps.
Click on the buyer profile link and if it redirects you to your profile dashboard then the buyer was a spammer and Fiverr removed the account. Don't worry.
