Complete and fix My blog navigation plus add comments

Must be experienced in Wordpress!!! Only bid if you are confident you can do this job or I cannot pay you. I have a fully working cross-browser compatible website and I had hired TWO FREELANCERS - one to create an integrated blog the match and the other to fix some alignment issues and complete the project. The blog is nearly finished but neither freelancer could not complete it or do the job I had asked them to do. In Firefox/Chrome/IE on Mac, PC and Mobile my site looks perfect - [login to view URL] In Firefox/Chrome/IE on Mac, PC and Mobile the navigation on the blog doesn't look the same, different size font, weight and alignment issues - [login to view URL] This may mean that my navigation may need to be completely rebuilt or coded using the same code on my site. Also, comment fields are not appearing on each and every blog post. You will have access to the Wordpress and my hosting account to complete this job. I am looking for someone to get this fixed without too much of my help. It should not take long at all as these are just "fixes" and no build or design. We will be able to communicate on Skype. As I have said in the beginning, please only bid if you believe you can fix these issues. Thanks
