When a user first joins, getting a breedable pet can be hard. The customs cost money, and often the bred ones cost a large sum of KS. Even for an older member, unless they have money to spend it can be hard. Customs also aren't always open, so even if one has the money the wait for customs to be available can be hard.
Vance has come to everyone's aid though and is offering a few of his personal breedables for users to rent out for breedings. He does have criteria that you must fall under though, as his services aren't for those that have dozens of breedables on hand already. If you'd like to check out what Vance is offering and see if just maybe you fall under those criteria, head over to his rental listing.
