Go through an agency : 

Everything is organized, from luxury trek to a day trip. Count from 40 to a 1000 dollars a day. Usually wapasi or tips are not included (See Baltoro). They generally target the most famous treks for routes a little more off the beaten track inquire. Find one of the many agencies on the net.   

Important: Remember to book your trek at least 6 months in advance for the setting of the groups; prices can vary depending on the number of participants. For the lucky ones who want to save money, you may be able to piggyback on a group already formed several months in advance, see directly in Pakistan. The agencies ask for a deposit, for Pakistan transfer money from bank to bank (see Baltoro) ...

Organizing your trek

Hire for a few days guide, porters, cook if necessary, etc ... Count following the treks 20 USD per day for the guide, between 1100 and 1500 rps.

The porters are paid per stages, sometimes two in one day, depending on the itinerary. In 2007 the official rate was based on a stage paid 300 rps without food (get food for your porter in this case) and 350 rps if he organizes his meals. This rate increases every year.

The weight that you give them is limited to 25 kg, it avoids the shameful drift of Nepal, where porters are paid by weight and even carry loads of more than 100 kg through the mountains! The 25 kg do not include food and affairs of the porter. The day you are blocked by bad weather, the porters will be paid one stage; it may be possible to negotiate them with rest days to a certain extent.

Think about wapasi, money which is necessary for the porter to return home. Do not forget the tips, to negotiate with all team members before leaving. Sometimes you will be asked a tip on top of wapasi; often it is the same thing. In principle, count for tips 10 to 20% of total wages; equipment left from your treks or expeditions are also welcome. For porters a day of rest every 7 days, and not every 7 stages, this day shall be paid half or a normal stage depending on the treks. 

Keep in mind that there are many possibilities. Which is valid in a valley is not in the other ... etc. Do not take someone on the way. Negotiate what includes the salary you pay, the best is to write on a piece of paper in front of witnesses (people from the village, the guesthouse ...).

Think that for a small amount of money you will help Pakistanis live, who have summer and a few tourists only to make a living. You will often be entitled to a royal welcome in families, and many doors will open in inhabited treks areas.

In case of accident as the crossing of the Passu glacier where some bodies have still not been found, inhabitants are can be held responsible if they left you go alone.
