Hey jaytyn, i'll start by saying good luck with the new business, all the best with it!
I'll give you my 2c from being a broadband user....
I assume with the price and "unlimited" download amount on ADSL that u must be another Comindico reseller. The ADSL market has sure become cut-throat lately with so many players entering the market. (Which is great for consumers and broadband uptake in Aus).
With so many ISPs offering similar prices for ADSL as you are (which are competitive btw), you'll need to stand out from the others. See if you can sweeten your deals by offering free extras eg. gaming servers, free downloads from certain local servers etc (These are just some suggestions, since some probably won't be commercially viable for your new business).
So many new ISPs popping up, ppl need to know that you're in it for the long run. That you're commited to them, especially in terms of service and support (especially on support).
It's "the" site for broadband users. Add your company's name to the list of providers, and if you have the time, create a post in the forum telling them who you are and what you have to offer.
again, good luck with your new business!
