Noob Mining Staking and Nodes Questions

  1. Hello, with ZenCash is mining the same as operating/staking a secure node?
  2. If staking, is the 3.5% reward proportional to how many tokens you stake or do you need to operate more nodes to collect more reward? i.e. staking 42 or 400 with one node.
  3. Are there any commercial sellers that sell rigs/nodes plug in ready, as in already software set up?
  4. Any consultants that can assist in purchase choices and set up?
  5. Cloud based vs home machine comments?
