Help - what do I purchase to use gmail

Help - what do I purchase to use gmail

Hi,

I signed up for the free version, but I want to use Zoho with the following
Google Apps/Gmail/Google calendar integration
LinkedIn integration
Access from my iphone

Can someone let me know what I need to purchase to do this?  I can't tell from the website.

I'm a single person consulting/coaching business so my needs are pretty basic from a CRM, but need the time savins on all the integrations!

Thanks

Sally
