I'm going to be honest, paying money for RPing assistance seems completely stupid if not a quick cash grab to me.
Photo Finding should be one of the first things in my opinion and that your character's written appearance should follow the picture, not the other way around. Also, most people you're on good terms with (and good people in general) are willing to help search for pictures as long as its nothing something insane like a monkey on a pogo stick with an AK-47 wearing a sombrero in Kazakstan.
CS writing in general is something that you put time and effort into as a sign of your interest in that RP; if you're outsourcing that then it says to me that the person isn't really interested in investing anything into an RP. And yes, history/bios are hard but that's just something people will have to suck up, sit their asses down and write. RPing in general is a labor of love, I can't begin to tell you how many hours of research I've done for NRPs or rewriting entire CSs for RPs that died and yet I keep putting time and work into my stuff.
World/Plot Building is something that in my experience is a collaborative experience between two or more people who share an interest in an idea and want to flesh it out; again, its a labor of love from people who want to flesh out worlds and want to see a successful RP come from it, not someone whose just in it for the money. There's also the issue of imagination and creativity (this also kinda goes with CS point above), there's no guarantee that what you come up with will be better than what someone else can come up with/worth the money.
I am and know others who help other people out giving them ideas and giving them direction for stuff like RPs and characters/nations and do it all for free as a sign of goodwill or something. Personally I am of the opinion that there is no valid reason to have to pay for the stuff you're offering, if you did stuff like character art commission then I can see why it would be acceptable.
Yeah, I do all kinds of stuff, including art commissions, but I should have been doing it for free.
One of my cats is sick so I was trying to earn a little extra money on the side to help with Medical bills. I'm kinda already 1000 dollars in the hole already.
But it was a stupid idea, I'll admit, I just wanted to get the money to help her as fast as I could.
I've already lost one cat to feline leukemia so if that's what she has I need to have enough money to pay for treatments.
Anyways sorry, you made some excellent points that I should have taken into account. Thank you for sharing your thoughts, they are much appreciated.
Have a wonderful day.
