Hi there, my name's Ignacio and I'm a WordPress developer specialized on that CMS since 2008.
I'll be glad to help you out with your site!
Regarding the slider, we can use a plugin called Cycle2, or similar, to pull the featured images from the last posts. Ok for the other details, including sidebar, avatar, instagram... and dropdown menu (do you want to keep the columnated menu? Or a single-row menu would do?)
I could to the work for 55$. Let me know if you'd like to work with me!
Best regards,
Ignacio
