We currently don't offer the option to customize CPU, RAM, disk space, bandwidth. Our packages are structured to offer the lowest prices possible while offering feature-rich service to meet your needs. If you wish to add more RAM or disk space, you will need to upgrade to the next available hosting package.
If you own an Ultimate hosting plan, it is possible to migrate to the PRO hosting service.
If there is no next Hosting package available, we would be happy to recommend you VPS/Dedicated service, which fits your requirements. Please contact our Sales department.
