Looking for a plumber to fit a new electric water heater

Hi
I have a friend who is looking for someone to fit a new electric 80 lt water heater to replace the old one that is scaled up
He has the new boiler on order
The sizes are almost identical so it should fit on the old bracket, it is in an outside porch so easily accessible and can be emptied straight to the floor drain so no worry about any mess
Can anyone recommend a plumber to do this and an approximate price ?
It is an apartment close to consum at la zenia
TIA
