i did not understand the LPG part but everything else sounds great.
Its nice to see you pioneering in a field like ISPs that is quite saturated .
Your point about Server Ownership is quite interesting for the general audience of entrepreneur's like me.
I forgot to mention in early 2015 i took a VPS for about 2000/- a month and 40GB space from ZnetLive , but i was not lucky enough to get enough customer traction so it was a counter productive investment and i retired it after 3 months.
Now I have gone back to using cloud hosted PAAS offering like openshift.com which gives me pretty reliable service to host my sandbox applications (upto 3 of them with each having separate technical stack and 1GB space).
For customers they will have to pay as per the pricing plan on an as needed basis.
Another colleague of mine uses Heroku.
If companies like yours can shift the center of gravity for cloud hosted applications to India and we can pay for PAAS hosting on similar lines as openshift, that would be so interesting.
All the best for your venture.
