Recommendation for hosting?

[Lvosspart]

Need a single cpanel hosting.
Some important features I needed:
1. Auto backup keeping and restoration period should minimum 7days.
2. Server performance and speed very important, no compromise with it.
3. Security
4. finally after sales support guarantee.
This is for our client of a Enterprise software. Very rare traffic will hit the application. Only 20/25 staff will use it.
Any recommendations please?
