The cutscene for meeting the maids will be different depending on which option you picked, where instead of custom ordering your maids, they've already been working at the club. In fact, you can edit details at pretty much any time via Maid Admin > Edit (this is also how you change outfits a maid is wearing). This isn't a big deal, since even starting with the base maid design lets you finalize details in the character editor before confirming them.

Selecting “Can you send them to other clubs?” will allow you to customize the three female leads instead of using the default designs. Secretary Maid will ask you if you want to meet the first three maids. Oddly enough, this is true of Guest Mode, too. Maids with v cards keep them until you take them in yotogi, no matter where they're working. I'll quietly point out that with NTR blocker turned off, having girls work in either Soap land or the SM club doesn't change their sex experience. You can't turn NTR blocker back on if you've turned it off, making it a one-way street. Soap land and SM club can be built for the master, but won't be legitimate facilities (can't be leveled or improved and your maids can't work there) and only add places for you to do yotogi with your girls.

Turning on the NTR blocker removes a large chunk of content from the game, more or less turning it into a great big harem. Since you're managing a club with maids as call girls, it's not unreasonable for someone that isn't the MC to be with one of your maids. The first thing the game asks you is whether you want to turn on the NTR blocker.
