SEO WOES, who to use and who not to!

Hi All,


I originally joined the forum here to perhaps get some pointers on get some better rankings on our site but since joining I am more confused now than before.

We get a phone call a week from companies saying they can boost our google ranking, most of them though can barely speak a word of English so I don't give them the time of day but it really is time for us to try and source more google search traffic..

So who to use and who not to?
I have got some quotes from both people within the forum and I have also googled SEO and picked a few from the top, figured a good company needs to practice what they preach hey. The quotes I have received vary dramatically some from couple of hundred per month and others as much as a $1000 per month

One of my biggest problems is we only ship within Australia so I figure we don't need to make sure we are at the top of the list for any of the global keywords which is why I was aiming to get an SEO company from within Aus but am I barking up the wrong tree?

hopefully there is a few people on here that have been in a similar situation and can give me some recommendations on who I should be using and what I should be paying..

Cheers
