I am really interested in helping you succeed in making videos of your travels; it sounds like a lot of fun!
I am a freelance videographer in Mississippi, USA, who in addition to freelancing, works on a marketing team for a University here. I have used Adobe Premiere and After Effects for years, so I am sure I can give you a great, professional looking intro and outro.
I also can assist you in the planning of this. Having seen and created a lot of video content, I have a good idea of what works and what doesn't, what is creative and what is cliche, etc. I set the estimated time to 4 days not because it takes me that long, but so that we have time to nail down a solid concept instead of diving straight into the quickest idea.
If you have any additional comments, questions, or concerns, please reach out by sending me a message. I hope to hear from you soon!
