Paypal is the way to go honestly

As for price (from expérience) start low and start slowly rising them up when you receive confused notes about your prices "wtf it's too cheap" :D

For real, make an estimate of your time to complete a piece then multiply the total of hours by the minimal wage hour salary

It's a good starter

Hope it goes well for you!

Let's be honest tho, pr0n or fetish pics is something who always work.

Also I don't agree with the guy under me about the number of slot. Go for 4, like a pic/ a week. If you feel confident after that, rise the number of slots. I tried the former and I noticed doing coms was very draining for me, the novelty quickly faiding up when you realise that, despite people coming for your style (or the fetish content you produce, let's be realist a second) there's usually a lot of restraints of what you are allowed to do (depend of commissioners and/or the "prestige" you will gain overtime, people trusting you to produce a good pic)

Again, I wish you good luck :D

Apron might not ask (and I'm genuinely curious), is there any tips on dealing with or avoiding "customer service" problems? Thanks!

Sadly I can't really tell here. So far all the guys I had were cool and despite my bad paying policy (being paid at the end) there was no problems. I am no fool tho as I tend to pic people who already have commissions in their galleries or "regulars" in a raffle (people I didn't pick in the first row but are still here the second, third...).

PayPal is the best way, have people pay ahead of time 100% of the time, unless you know/trust them.

Draw whatever you want! With your style, though, I'd back away from porn/fetish/NSFW, because to me, your art is super focused on atmosphere.
Not saying don't do macro, because you do it fantastic.

Price them how you feel, either by quality of art (sketch, flat color, shaded), however I see you usually push out the same type of art which is the vector/shaded stuff, so I'd say charge by the hour. Most artists charge $15-30 an hour, depending on the piece. Let people know how long it'll take/give an estimate.

Start with 5-10 slots(depending on how fast you work. People get pissy if they wait >1 month in a queue) and then move from there with what is comfortable. Don't burn out!

Definitely do macros, that's 95% of your audience here.

If you do end up opening, I'll order in a heartbeat, hope I helped!

paypal is definitely a good option since it's widely used and trusted, and you can get paid before starting the commission so you won't get ripped off. I agree with others that charging by the hour would be a good start, and maybe after taking a few you would be able to adjust the prices to what fits, or alternatively you could price it in tiers by starting with one character on a white background, adding more to the total for a scenic background, additional character, etc. not having regular internet shouldn't be a huge problem tbh if you can still draw offline!

Sometimes they'll have some additional options for payment, but PayPal is what practically every artist uses in my experience.

I honestly don't like telling artists what they should price their work at, I prefer that they do whatever works for them.

If they plan to do furry art full time, I usually suggest they start with low prices to attract an audience and raise them over time as their customer base grows. If it's just a side job for getting a few extra dollars, I don't think that there's really much of a formula to worry about.

Starting off, I'd recommend a limited amount of slots. Take too much on at once and not only could it be overwhelming for you, but requires more commitment to your original plans too. Starting with smaller batches will be a lot less risky. I see a lot of artists ending up running monthly openings, but there's no right or wrong way to do it. I see tons of different approaches to it that all work.

I say yes on drawing anthro, but asking something like that here is going to give a lot of biased responses.
