Hello Asim,
Pakistani is a nation of people who have great hearts when it comes to helping others. Unfortunately our leadership, ministers, embassies and government officers are corrupt and greedy.
Your sincere attempts to pool any money to be spent on poor or needy will be looked at with a lot of suspicion and mistrust which can not be blamed as 95 % of such schemes turn out to be scams.
It does not mean that we stop worrying about other human being, I suggest we take the following steps:
1) Work under the umbrella of an already established group eg EDHI Trust and Ansar Burney in Pakistan, get the legal requirements straightened out for collection of funds.
2) A lot of Pakistanis are in middle east Jails , lot of women and kids are stuck in different cities, I personally know 5 Pakistanis whose passports were stolen and they are in Riyadh jail for more than a year waiting to be deported. Small groups of Pakistanis can pool their resources together, hire legal services , pay fines and penalties and help them return to Pakistan. This does not require rocket science
