add google maps

hi

i wint to add a free version plugin for google maps

it has to be able to add my adress in it and i must be able to put it on the company page

is there such a plugin ?
if yes wich one is it ?

i already installed 12 plugins and no one was good either they ask alot of money for it
or it works with some kind of api key and you either have to buy that or it does not exist anymore

some advice would be nice
thnx and grtzzzz
