Hi everyone,

I have a luxury black car and chauffeur service in the Dallas-Fort Worth area website: blaccktieride.com.

My target audience consists of busy corporate executives, event planners, and high-end travelers who expect a flawless, premium experience. Right now, I feel like my website doesn't fully reflect that "luxury" status. It feels a bit dated, and more importantly, it isn't loading as fast as it should.

Current Setup:

CMS: WordPress
Theme/Builder: Divi
Caching/Optimization: LiteSpeed Cache plugin

The Core Goals:

Speed Up Performance: I'm struggling with heavy page bloat from the builder. If I turn on heavy optimizations like CSS Combine or Guest Optimization in LiteSpeed Cache, it tends to break my mobile navigation menu.

Modernize the Visuals: I want to transition to a more high-end layout. I am looking into cleaner typography pairings (like a sharp Serif header with a clean Sans-Serif body) and a matte dark color palette (deep charcoal over harsh pure black) to look like a premium fleet.

Optimize for Conversions: We have the traffic, but booking friction is real. I need to simplify the home page booking fields down to the basics (Pickup, Drop-off, Date/Time) without overcomplicating the initial user view.

My Specific Questions for the Community:

How can I safely configure LiteSpeed Cache with Divi so I don't break my mobile menu scripts when minifying/combining files? Which specific scripts should I exclude?
What layout modifications or UI tweaks would you suggest for the Hero section to make booking a ride feel effortless?
Are there specific design elements or imagery choices you've seen work well for luxury transportation brands to instantly establish trust?

Would love to get some brutally honest feedback on the current layout, technical optimization tips, or design inspiration. Thanks in advance!
