DO NOT USE A NUMBING AGENT. DO NOT.
I'm a big chicken so I thought it would be a good idea, and I actually had a MUCH harder time with those tattoos than I do now with the others. Doing it naturally, your body builds up a tolerance to the pain and the only difficult part for me is the 'burn' of skin that's already been tattooed. The sting to me hurts worse than the actual tattoo. If you use a spray/gel to numb yourself then all of the pain hits all at once and it SUCKS.
Grand total I have seven tattoos, but one of them is a 3/4 sleeve we've worked on in multiple sessions. Two of them were done in old-fashioned tebori- which I don't recommend until you've done a modern machine tattoo because you need to know how to deal with the healing process, I had more trouble with those than with the machine ones.
As I said, I'm a huge baby, I cry when I stub my toe. I'm also terrified of needles and getting my blood drawn is hell.
BUT I'm addicted to tattoos. It's an entirely different experience. The whir of the machine is lovely white noise and the pain isn't actually that bad, your body handles it. It's very soothing and relaxing to me at this point actually xD
The pain isn't as bad as you're afraid. The only parts where I got a little stressed was when he was on the inside of my knee, my elbow, and the inside of my arm near my armpit. Tattoos on my thighs, upper arm, inner arm, and lower leg have all been totally fine.
As far as money goes I don't think it's too bad? I've paid $350 (with tip) per 4 hr session for my sleeve, my small memorial tattoo was $150 with tip, and my shop runs an AWESOME event every Halloween where they do tattoos for $50 so getting established somewhere is a good idea if you want to keep getting tattoos, events like that for regular patrons are pretty common.

I highly recommend ibuprofen and ice after you get the tattoo to prevent swelling, I found that the most irritating part of the healing process. Be very careful not to keep it TOO moist. A tiny amount of bacitracin the first and second day each time you wash (I do once in the morning, once in the afternoon after work, and once before bed), light unscented lotion for a week afterwards. Make sure you wash with delicate, unscented soap.
The WORST part is taking off the covering after sleeping on the tattoo the first night, the ink run-off makes me want to vomit.
You can message me if you have any more questions ^-^
