Hi, I'm looking to advertise my Ioffer account, which has about 5,000 listings on 1 Twitter Account nd 1 Facebook account, which Ioffer will allow me link my account too 1 of each and no more. I'd like to know what kind of link building, seo or other advertising marketing you can do for me to get me hits, I could pay based on sales and could pay good. Or I could pay for what you do for me, I'm open to whatever. Just looking for 1 Twitter Account and 1 Facebook Account (doesn't have to be mine or include my information), just need 1 account to link my Ioffer inventory too and hopefully build up my connections and friends and my number of followers.
