It is necessary to modify / something to redo in the site on the Joomla engine

It is necessary to finalize / something to redo in the site on the Joomla engine.Dano- there is a site on joomla, hangs for a long time idle on the domain in the com zone. Version 2.5.28, i.e. quite old. It is necessary to carry out all the necessary updates of both the joomla itself and the Virtue mart module. Its a one-time. Next, something to redo / finish in the structure of the site, add / remove sections, etc. and transfer it to another domain for further work of the site in the furniture theme.. No idea how much it might cost, offer options, put the minimum cost so far. In general, I would like to find a contractor to work on a long-term basis in order to add further content to the site, support, etc.
