ERPNext WHMCS self hostinf

It seems not all the ERPnext plans allow for customised development. So I now need to look at self hosting as my some clients have specific needs.

Does anyone know if there is a way that this can be done automatically using WHMCS? Similar to how Softaculous works where when a customer purchases the hosting they then select the app in cpanel of what they want such as WordPress.

I have seen bitnami has ERPNext applications but you can not automate the hosting process and payments.

@Softwareprofs we are happy to look at custom apps if you sign up for the $1500 plan
