Hey mate, so, from one traveller to another traveller, congrats! I'm a software engineer but also a tourist, I'm from Argentina. So, I like your proposal and I'm willing to deliver a nice website for you so you can continue travelling around the world and maybe some day you can visit me here at Mendoza :)
Technical details:
I think what you need is a wordpress site, why? Because Wordpress is the best CMS I know, best than Joomla, Drupal or any other CMS (Content Management System), also, SEO is the main focus on wordpress site, also you have thousand of plugins if you want to implement something new/cool, like google maps, facebook comments, custom feeds from another site, ... Well, wordpress is definitely what you need, even if you choose another programmer for this job, please, require Wordpress.
About myself, well, as I said, I'm interested, not because of the money, I'm pretty new here in freelancer, instead, the project you host is interesting.
So, let me know if you want to start, I'm ready.
