Refine UI/UX for simple community matching wordpress site

I mocked up a basic concept in wordpress (how-to-hunt.com), but need someone to step in and refine it for mobile-friendliness and credibility. Some of my hopes include: 1. General UI polish. Help with fonts and other visual elements that make it consistent with what users associate with a professional (but casual) website, and that ideally show up well on a mobile screen. 2. Member/community UX. I am leveraging the Ultimate Member plug-in for member profiles. I would like this initial project to make some simple changes that make the sign-up and peer search flow feel a little more smooth. 3. Depending on time, I would like to revamp the menu structure on the page, as the current top menu feels clunky to me. I would want suggestions here. This is still a proof of concept, so I don't want to overinvest before making some larger decisions. The intention here is just to get the appearance and user experience to an MVP level. I would like to find someone who has previous examples of work that have a similar scope and vibe (simple, clean, casual). I am able to answer questions and talk through as needed, but I want this to be an efficient project where you can spend something like 1 hour on discovery and basic planning, 4 hours on the work, and 1 hour talking through it with me and making 1-2 small tweaks as needed. The actual breakdown is absolutely flexible, and the scope will depend on hourly rate. This would ideally be done across 2-3 days.
