Have a look at this, unless you want something
other than constant radius.

Hi Filippo,
Are you looking for something like the large ovolo bits Amana offers?
If you want a shallower cove profile you can use a core box or round nose bit of a larger diameter and not use the full profile.

Whiteside will make you anything you want in the good ol USA to boot, and won't skin you in the process. My dad and brothers have cabinet/furniture shops and have had several bits made with great results.

Give these guys a shout. They should be able to fix you up.

It might help to know the dimensions of the rout you want the bit to make and what use you are putting it to. If we understand the problem we might be better able to suggest solutions.
I make large shallow coves using a table saw and different diameter saw blades. That is how I generally shape the heel on the guitar necks. Radius dishes are large flattened coves in cross section made with various methods. More than one way to skin a cat.

I think if you search for "Corner Radius End Mill" you'll find what you're looking for.
