Looking to resell quality LinkedIn automation tool

I have been using Massplanner with interesting results on LinkedIn and am looking to resell any similar tools out there.

Massplanner is pretty reasonable at around $10 per month and I would like to try reselling for double this amount but ideally diverting any support queries back to the original developer(s).

Thanks for your help!

How could you resell it?

The buyer would have a massplanner license and would see it was a third party software.

So you want to double the price, what happens then when the buyer sees the real price?
There seems to be a flaw in your business plan OP
