if you really want to get business here are two things id do..
1. support the site. become at least a premium member. guys on here are loyal to people who help the site. FAST, NOSS, M&M etc... they have tons of repeat buyers.
2. port someones cylinders for FREE. yes i said it.. FREE. someone out there needs something done. offer to do it.. if you do a good job, the word of mouth will be well worth the time you spent porting those cylinders for free.
