I'm sorry you are having such a hard time. I have found that e-mailing pilots is more effective. When you click on "Other Mapping Options" at the top of your posting and then click on the first link that gives you the pilots on your route, when their profile "bubble" comes up, click on the first link to view the pilot's profile. Once that is up, on the bottom left, click on "e-mail (profile name)". The e-mail box will come up. Put in your subject line "PNP Request: from and to locations. Then I try to give brief but thorough information as to what I am asking of them. If I have a pilot for one leg, I will say in the e-mail that I have a pilot from where to where and ask if this pilot can do another leg and if so, how far would they be willing to go. I send multiple e-mails (by copying and pasting) to 10, 20, 30 pilots. If I don't get any responses, I'll go back and continue down the list. I usually always get the trip filled eventually.
You didn't say how far your trip is. If it's a really long trip requiring multiple pilots, that's a bigger undertaking and often very difficult to manage. The other thing that is affecting pilots now is the increased fuel prices. That's put a big dent in the amount of trips pilots can do.
