First of all, if you can pick up multiple waitresses, then just do that. You'll save yourself a ton of cash. I, however, am way to old, slow and fat to do that. So the sugar bowl is my playground (plus pros and various strippers either in or out of the club).
As to WYP strategy, I've previously posted extensively on this, so please do a search for a comprehensive understanding.
But since, I assume you are at least as lazy a fuck as I am, here's some top-level notes:
1. Look for focus: only consider profiles where she has selected sugar dating as one of the dating types. But stay away from the wide-netters who check every dating type. There's no way she's looking for casual, sugar, married dating AND married minded.
2. Read the words carefully and find those who imply fun for sugar. "I need help with _______" is good. "I deserve the finer things like ______" is bad.
3. Think of the 1st date cash (usually $100 or less, unless she's super hot) as part of the meet & greet expense. Pick a cheaper place to eat (or just go for drinks) if you need to stay in budget. Then NO MORE CASH until you've agreed to BCD. If you're going to have a 2-4 month arrangement a $200-$400 per meet, the extra $100 first date cash will mean nothing over time. If you are selective on date offers, you should be able to convert anywhere between 35% - 75% of your dates. About the same as SA.
4. CRITICAL: Don't be a dick. These POT's are either new to sugar or just not really sure they want to p4p. If they are not just professional lunch eaters, they are skittish or insecure. They will bail on an asshole as soon as they get as much cash as they think they can get. Note: High achievers in college are lunch eaters. Struggling retail clerks at community colleges will suck dick for sugar.
5. Be honest, but not graphic. Let them know that your intention is to find intimacy in addition to the dating stuff. Don't make it your 1st priority, just keep it in the list. Stay away from acronyms like NSA, FWB, P4P, etc. Be a "normal' guy who is trying an alternative to bars and clubs because you're tired of the posers.
