Bot generating pageviews via proxy - Alexa friendly

For answering a client's needs, we want to increase a wensite's Alexa Rank while keeping stats on google analytics high > good bounce rate and good pageviews. Buying cheap popup traffic would increase alexa rank, but would lower overall bounce rate and pageviews. Thus we want to develop a bot that woud emulate "quality alexa traffic". We need a bot that would : * navigate from site A to site B by clicking on links. * once on site B, the bot would follow certain patterns and navigate a few pages before stopping * use Alexa toolbar in a browser * use proxys * be identified as using a browser in analytics We found several services doing this as "traffic exchange / autosurf" but all of them lower bounce rate & pageviews stats. So basically, this soft would be a customisation of something like "Hit leap". We believe that tons of these bots have already been developped so we hope we can find someone with experience developping this kind of projects. We're available for answering questions and giving more details, thanks in advance for your interest !
