Start slowly and try and source stuff locally, ie. dont ask for stickers in the UK when you can get them made in Oz, find somewhere there.
It isn't easy, the internet is fine for selling but be aware that if you to have ask questions about products and the whys and therefores on cricket equipment and you are selling stuff yourself you aren't really ready to sell to people as you are still learning yourself and people buying from you may have more knowledge about it then you have. You need to be equal of above to meets those customers needs.
Dont try and take on the world or push out stuff you are nervous about and will need to email people about every other day to find out how it is going. Research quietly, learn all you need to, sell locally and build up a reputation and the brand slowly if you are really interested in doing it long term. Get comfortable with seeing your stuff being used and people using it, build up a reputation there and then if you are happy and players are happy and word of mouth is working locally, expand out.
I've seen, answered and watched a few people startup with little or no knowledge it is both amusing and scary.
