In reference to your proposed seedbox plans:
- would suggest adding plans with higher HDD space
- are you going to offer 1Gbs network speeds?
- would add Transmission and Deluge to the list of webui options...give people more choice
- what RAM and CPU will be on your plans?
- how many users per server & HDD?
- is root access available?
- are plans renewed monthly?
Whether pricing is reasonable or not depends on some of the factors above
There are quite a number of seedbox providers out there so you need to differentiate yourself amongst the competiition. People do change providers quite often in order to find the "right" seedbox.
