I have already finished budgeting and finalizing my activity and location. I also received some quotations for the items I would be buying and finalizing on how the pick up can be done. I will update my progress here as well.
Don't forget the water since flood victims need clean drinking water, I saw it on interview that they are asking since they don't have any available for now.
Also if there's extra budget they need boots since the roads on every streets are muddy and they need that for extra protection.
I included this in the budget and I would probably include 2L only. It would provide better mobility for the package as well. I like the suggestion of @jamyr but I'm concerned about how they would use it though.
Regarding the shortage of available drinking water, it is more efficient to carry aquatabs because it is very heavy to be carrying that especially in Tuguegarao. The bigger challenge is explaining how aquatabs work.
I'm not sure people would trust to see these tabs and would use it correctly. It's the best solution for the transportation problem but I'm not sure how they would use it correctly. That's my only concern. I would opt to use the bottled waters already and would just hire bigger transportation for it.
