I want build VMs for an open source project (https://github.com/frappe/erpnext). This requires booting a vm and exporting its image. VPS services like DigitalOcean and Linode are superslow. I didn't have much success with Travis-CI as well.

My current setup is ansible + packer + virutalbox and it builds quite fast on my local.

Is there any vm build service that we should be looking at? $10/mo seems to be a good budget for this.
