Simple Wordpress PHP Fix

I need a two very simple fixes done within the PHP of my wordpress theme's functions. 1. I would like to add pagination to the home page. Currently the site has a pagination function, but each pagination link is directing the visitor back to the home page. 2. I have a related posts area on the bottom of each post page. Currently, it is displaying the most recent posts rather than other posts that are in the same category or of similar tags. I would like the Related Posts to show other posts with the most similarity. These php functions are already written and I will send them to you to make the fixes. These tasks are quick and easy, and I have a very good idea of how much it should cost. If you are under the impression that you can overcharge because I may not know much about PHP, please do not waste a bid. ****Payment will be released once the fixes are entirely completed to the standards that I have set forth above. ****Candidate must speak fluent English If you can complete this in a timely manner (within the timeframe that you state in your bid) I will come back to you for more customization in our website. Thank you for looking.
