I'm not a customs guy but I know this much: don't use OF for it. Use Manyvids, it has a proper system for it. The model isn't paid until the order is filled. You're also likely to get a much better one anyway.
Other than that, some general advice for newcomers:
Be judicious about who you sub and spend money with. Ultimately most OF models are disappointing in one way or another, be it with activity or post quality or commitments. And that's not even mentioning the outright scams. Most of us just have to go through trial and error but there are some general methods.
Models with subs in the triple digits or more are likely paying somebody to do messages, so don't expect real interaction.
Stick to smaller models if you're into anything like that. It's also nice to be paying someone to whom the money and appreciation is actually important. The major pitfall there is that many of them give up and quit.
Be aware that with any 'big' pages you're basically just subbing to a porn service but with only one model. There's nothing personal about it.
Camgirls are pretty decent to consider, for several reasons. They're often more professional and don't outright exploit people (some do but it's much less common than average OF thots). There's a decent chance you're actually interacting with them because they're used to doing it in their chatroom all day, they don't need a "manager" (again some do, but in general they just take it way more seriously than average models and know how to handle it). Their prices also tend to be decent. Plus you know they're open to a lot based on what their streams are like.
Of the, at this point quite a few, models I've tried out the 4 I've actually stuck with are all also camgirls. I believe it's a telling trend. They all communicate and they all post excellent stuff. These are those few models who I'd never leak, or even identify them here, because I genuinely respect and appreciate them. Seriously, look into camgirls. You may find some keepers too.
Don't buy anything off Snapchat because it has no verification method and it's full of scammers. It's either a dude or maybe she's actually real but she won't send you anything, or very little. The only snaps I have are from actual model pages, meaning I know it's them. Never do it the other way around.
Finally, this might sound cringe, but listen to the Hall & Oates song Man Eater. I'm not kidding. Listen and understand the lyrics. Apply that message to models and you'll get what most are like.
