Change Plugins To Script and fix 1 bug

What we are trying to do is fix some issues and make the site load faster by replacing it with relevant code and also fix one issue with the blog. I have a Wordpress site and need the following thing fixed: 1. The blog page has stopped working, it comes up as a white blank page when logged into WP and no blogs show up on the live version. 2. I have custom 404 Error page code (for custom 404 error page when it loads). I want this put into the child theme (code given when job started). 3. We have a "no right click image plugin" to prevent right clicking and downloading images. My SEO people told me there was a script that when someone right clicks the image to download from my site that they will get an image with a water mark. We want to remove the plugin and replace it with a script that does this. 4. Replace the plugin "WP Force SSL" and replace with code. 5. Replace the plugin "All in one Favicon" with code that does the same thing 6. Everything listed above must be done AND put into our child theme. To be considered for this job please place your answer for the following questions at the bottom of your bid (not the top), the question is what is nine plus four.
