Really?, at least wasn't be ilógical from my part
you see, once happend the same to me, but it was a little diferent...
in my case i put it like a Help request, and he (the other guy, diferent than this one) says "i'll help" in the public post, and for pm he try to put a charge...
i accept than this section is the Job Request, but there is 1 or 2 intresting things about it.
1) He doesn't estipulate payments in public (or the fact than you must pay it to him) that's not something weard?, he think probably he can do what the other guy try to, it's just call me deeply the attention why he don't make public the fact that he was looking for money since the begining?, it's not a moral trial it's just about honesty, it's about intentions.
Apparently not even him seem like something good... he must know perfectly than hims prices are extremely high and unproportioned
isn't this intresting for you?
2) indeed i invite it to my proyect, but was because in that moment i was justified in believe than he can accept something like that, because of that i let the rules clear from the beginning, besides i don't lose nothing with try, did i?.
& tnx to the information he post i can (and in fact, i'll do) assume than he can accept a proposal like mine, because him's motivation can be other different than $$$ (Whichever this will be like me and the guy who is helping me mapping).
And in case than you wanna question the others part of the post... Perfect, you can start defining "art" and defining the space of the same (asuming thats the part who inspires you to make that answer

)
¡Have a Great Day!
¡Bless you and Cheers up!

PS: @Kregox if i was you, i'll put the price thing on the main post, that way if someone wanna pay you for your work is going to contact you with that condition, otherwise i don't see the point, put a suscription on this topic wasn't a bad idea from your part if you do what i propose.
