Eduardo: If you need IMDbPro, you can subscribe to it (http://pro.imdb.com ).
However, make sure that IMDbPro is actually what you need before you pay for a subscription. If you need to update the credits on your IMDb name page, for example, you can do that with a free IMDb account -- not using IMDbPro.
If you explain exactly what you are trying to do, the contributors and staff here can advise you whether you can do that with a free IMDb account or whether you will need IMDbPro.
If you have any questions about submitting data or updates to the site, as gromit82 mentioned above, please post the additional details in the thread here so we can help. Thanks!
