Need an option to have more than 500MB storage

**Is your feature request related to a problem? Please describe.**
My site is bigger than 500MB.

**Describe the solution you'd like**
I would like a billing plan that has an option for up to 1.5GB of storage.

**Describe alternatives you've considered**
I can store the assets somewhere else, but that really defeats the point of having a single solution for our website.

**Additional context**
