@KingArmand I'm not sure exactly how much tattoos cost where you are, but larger tattoos (i.e. spanning a forearm) will cost about $150+ minus tip. I always tip 20% but that's on you and your budget. You might be able to find cheaper, this is all based on what I've found.

I like my tattoos to be collaborative. I give them the idea and I like for them to design it the way THEY feel most comfortable. They should always show you a stencil/sketch before they start working. You shouldn't feel pressured into saying yes.
