Shared Hosting Plan with Lots of Memory?

Hi guys, I'm not sure if this is the right place to post this, but I
am looking for a shared hosting plan for my website that offers a lot
of memory and processing power.

I would go with a dedicated server or virtual dedicated server, but do
not want to deal with setting up my own email, php, mysql, etc.
servers on it. I want someone else to maintain the platform (with
security updates, new versions of php, etc.) so that I can focus my
time on development work.

I basically need a shared hosting plan on steroids.

Does anyone know of any good plans like this?

Thanks in advance.

Karl
