Volvie: exactly why a middleman is the best way to go (if you can trust them) as per BB 10B. None the less, there is still a concept of the Ani himself going from door to door (see there).
estherh: That is 100% Shelo K’halacha, and I am surprised you did not learn so at some point in your education. There are specific examples when you give without asking (food), otherwise you are Mechuyav to ask and investigate, and then be makdim some before others (BB 9A, SA Yore Dayah 251 sk 10 & 11).
Ask your Rav what you should do.
