Check out Rise ….nice interface… you control the billing of the customer and even ability buy short blocks of processing power as needed for a server project.
I met with them at booth 100 at the WPC. I was impressed. They have some good stuff going on and ability to be your cloud provider. I can’t do it justice, nor can I show you the cool server provisioning interface that I saw at the booth. My advice is to fill out the contact form and ask for a demo.
I was impressed.
