Hello everyone!I am considering to

Hello everyone!
I am considering to do some volunteer work abroad (in October or December) for 3 weeks, preferably with kids!
Does anyone have a recommendation for me of a good, trustworthy organisation (that charges a normal price for joining) or a positive experience to share with me?
There is so much on the internet :S
Where? Depends on the costs (travelling, costs to volunteer work, living etc.), at the moment ‘everything’ is still possible but my budget is limited.
Thank you all, I am curious to read your replies and who knows what they will bring for inspiration to realise this.
