I agree with sewing as the best strategy. Obviously, that means a fella can't swap out a temporary patch but once a year while taking online YPT (that might be the only spare time someone has) ... so choose your absolute favorite. Mine's been on for nearly 40 years (actually hopped from shirt to shirt once ).
Are you referring to temporary patches as worn on the right pocket?
I just sew them on when I want to wear them on my uniform. When I want to switch out the old patch for a new one, I remove the former with a small seam-ripper, then I sew the new one right on the pocket (by hand so that I can still use the pocket). The whole process takes only 10 - 20 minutes depending on size of the patch. So far, none have ever fallen off my shirt. So, my experienced recommendation is: the ol' needle n' thread.
Our troop charges $30 above the required fee. This provides a necker, slide, patrol patch and advancement/MBs the first year. All campouts including summercamp are charged separately in advance.
Try and network. Does someone's grandfather or someone at the CO own some property where you can camp? What about shooting sports/hunting clubs in the region?
beg and borrow equipment in the beginning. many communities have facebook pages devoted to local happenings, post that the new troop is looking for tents and items that might be taking up space in someone's garage. people are happy to help the scouts when they can and maybe that old tent will only last a year but by then there should be some fundraiser money in the bank. Also, depending on what tents you eventually buy, do not pay retail! Several companies give scout discounts on tents.
we sell popcorn and do an annual fundraiser as well. the two combined replace any needed tents and purchase any new equipment like staves or rope. our troop also assists with leadership training costs so some cash goes there.
They took "A Scout is Friendly" to a whole new level. I was once the District Rep on an EBOR and as we were reading the letters of recommendation, one was from his sister who was heaping praise on her brother for being such a good father. The two were still "living in sin" under her parents' roof. Well, the Troop Committee members were livid, primarily because we were blindsided by the SM who thought it wasn't "relevant". It was not a unanimous vote. The scout appealed to Council, who rubber stamped it. The CO was a Methodist Church.
