Zend certified PHP/Magento developer

using my google account to fully manage a profesional account [closed]

may it be done?

details:
I have myPersonal@gmail.com account
and I got in charge of managing a profesional@ownDomain.com

I would like to manage it all from my personal account, or at least from a google account I own. So far I can do two things

a)
forward all email from profesional@ownDomain.com to myPersonal@gmail.com (asked webmaster)
add profesional@ownDomain.com as alias myPersonal@gmail.com (and validate it)

b)
create a new google account with profesional@ownDomain.com

but PROBLEMS:

a)
calendar and other gmails tools are ONLY under myPersonal@gmail.com
(even I can send emails as profesional@ownDomain.com )

b)
I do not have email interface for profesional@ownDomain.com, even the rest of the services works with this address

THAT SEEMS SO CONFUSING

I have try to add the professional email as contact info, and other different things, but it seems that I cannot do both, send emails and use the other gmail products with the professional account

The webmaster say me that the domain is not on google, it is for a stablished company, and they will not change obviously only for me.

May this be done, or it is an impossible?
