Looking for results-driven PR professional: write and distribute press release

I am a young Scottish entrepreneur looking to push my user experience or digital consultancy services in Sydney, Australia. Since arriving here in Sydney I've been fortunate enough to work with a number of high-growth startups, 3 projects have been featured in the Australian press, one raised investment, one helped students.

Essentially I am looking to raise my profile in the Australian marketplace. I am hoping that the exposure will also drive traffic to my personal webpage and increase the number of enquiries for either consultancy work or freelance projects.

A few questions:

1. Do you have any established contacts or see a barrier to distributing in Australia?
2. Can you please provide web links or examples of previous press release work?
3. Do you have experience in dealing with technology editors or websites etc?
4. What results can I expect?
5. Why should I hire you?

Looking forward to hearing from you.

Regards,
Ryan
