Re-Build an Existing Airport Shuttle/Tours Website and SEO

My current website (www.rapidshuttle247.com) is getting a lot of "bounce back" rates Trying to make a more friendly user website to increase the rate of conversion.
I'm looking also for the following Digital Marketing services:
- Search Engine Optimization
· Social Media Marketing services (Facebook, Instagram, Tweeter, Linkedln)
- On-Page SEO Services
- Local SEO
- Off-Page SEO Services
- Lead Generation

10 yr old website (www.rapidshuttle247.com)
Service term: Long term (our current DM has been with us for 2 yrs +)
Reason to change our current Digital Marketing Co.: Not happy with the results.

If you could provide us with a plan of action and a quote, I would
appreciate it very much.

Respectfully,

Paulo
