Three existing websites are to be implemented as Joomla sites on my personal W11 computer. All should be ready to go as is, without manufactured nor freely available nonstandard equipment. All components should be standard and freely available online. Softaculous applications will be preferred, since they already specify the installation of personal computer copies in their documentation. Internally, the applications will be updated in the same way that a Joomla 6 functions. Interaction with the official websites is desirable, but not required. What is the proposed cost in Euros?
