Hey buddy whats up? Alright I’ve been in similar predicaments about money and “teaching”. I’ve taught club classes on solving Rubik’s cubes, and didn’t have the money to pay for Rubik’s cubes (10 dollars roughly per cube). What I did was: I has for a 10 dollar fee from everyone as a “class due”. It worked out because I told them my time isn’t cheap (its a job). But what I did was I used that money to buy everyone a Rubik’s cube. This way it shows determination on solving and shows that they aren’t going to be wasting my time. Also they get to keep the cube to work on at their homes, theoretically they learn for free. With this system I always had people learning and people came to my sessions because they paid to learn (that’s just simple psychology).
What I recommend you do is get the projams. The reasons I say this is because there aren’t that many good yoyo’s under 5 dollars that are new. Also Mosquitos are 4.50 at some wal-marts and around 6-7 dollars are other walmarts. Those are cheap and will get you as far as intermediate. The only down side to those are the friction stickers, they fall off and then you have to replace them and that’s costly since my stickers feel off in a week. With the starburst in the Projams won’t wear off that quickly it’s something that they won’t have to replace (that’s good for expenses). Also they will have less to worry about with the projam.
Also something to think about is you might want to tell them up front that most yoyo’s pros buy are pricey ($50 or more) and if they think 5 dollars is rough then they might want to reconsider their choice in hobby (say the last part only as an option even though its true).
So I recommend you asking for some money, word it however you wish to word it but ask for around 5 dollars so that you can get a good beginner yoyo. In the end this will help people appreciate what they are going to learn and they will appreciate you for teaching them. I really hopes this helped you even the slightest bit, and if you need more “info” or just more ideas I’ll be checking up and you can also PM me and I’ll help you out more if you need it. It won’t bother me because teaching and helping is what I love doing in the first place.
