3 Simple Wordpress site works

I would like you to help me with the following tasks on my WordPress website, and I need them completed within the next 2 days. Here are the detailed instructions, only bid if you are going to bid below 75 $. I have already installed configured this plugin, but needs more modification. Gravity Forms Plugin: Minor correction needs to done in the gravity form configuration such as changing field name, css and jss conflict issue renaming, auto confirmation email upon approval. Photo Contest Plugin: Configure the plugin to create weekly and monthly contests. Once registered, participants should be able to log in using single sign-on via Facebook or Google. Participants should be able to post pictures, share them on their social media or website using the permalink of their picture. Allow people to vote, rate, and comment on the pictures. Automatically announce winners based on the highest rating and voting. Enable weekly winners to participate in the monthly contest automatically. Set up prizes as follows: weekly winners receive a buffet for 2, and monthly winners receive AED 100.00 and an Ambassador Card. Site Optimization: Optimize the website for faster loading using the WP Rocket plugin. XHTML Validation: Ensure the site's code is valid XHTML, as per W3C standards. I look forward to working with you and achieving these goals for my website. Please let me know if you have any questions or need further clarification on the [login to view URL] site presently up and running, all these plugins already installed, some need additional configuration, or custom coding to complete the task.
