LOCATION AND COST OF PRC BUSINESS VISA IN MELBOURNE

My business partner and I travel to Nanjing on 04 November 2011 to attend Greater China Travel Mission. To obtain our travel visas we wish to attend an office in Melbourne on Tuesday 13 September 2011 (Monday 12 is a holiday for Mid Autumn Festival). We are unsure of which office most appropriate to visit. The Consul General is at 75 Irving Road, Toorak. The CVASC is at 534 Toorak Road, Toorak. Another office mentioned on your website is PART Ground Floor, 570 St Kilda Road, Melbourne. If we go to the CVASC to we incur an extra service fee? If we go to the Consul General office is the total cost 2 x $40 = AUD80.00?
