uping you conversion + PPC. that way by that time you are in the SERPS rankings, Your conversion process is great and you will really start raking it in. some article marketing for your niche just preselling people onto parts of your site would work great too.
PM the link if you'd like, I'm curious to take a look. I agree with others, PR will have nothing to do with sales or traffic, sure, if you have a PR of 8, we could "assume" a generous amount of traffic, but is it "buyer" traffic or looky-loos?? The object is to score qualified buyer traffic. We want people to get there wallets out when visiting our sites! Say for example someone is looking to plant roses in the yard, and wants to look at different varieties before going shopping, and you have a website that sells a dozen cut roses for $25, that person isn't a qualified buyer. You need to concentrate on search terms your prospective buyers will use. Good luck
