Consultant

I was thinking after quite a couple of my friends keep on sending me PM on msn / ym for help, I was wondering if I should do some part time and charge them as their company want's to do a project yet they don't have the knowledge to do it. I think it is nothing got to do with kedukut ilmu as everything is on the Internet and can be done thru research but as usual we as humans we want things to be done fast and the shortest way as possible. But now the thing is, if I do help my friends, will their company pay me?
