Fix some bugs of my wordpress site

I have few bugs in my wordpress site. need someone to fix them. Most important one is that when I search with topic that was posted to my site on google, the archive page comes ahead of the original page for that topic. I would need a wordpress expert to fix these issues. Also need to check if my site has a proper navigation system. Someone having knowledge on google adsense will get priority as I have some adsense related task as well but I can hire a different person only for that adsense part. No problem with that. Thanks.
