All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His Slave and Messenger.
The scholars differ regarding the obligation of Hajj, whether it is an immediate obligation or can be delayed. Those who consider it obligatory with flexibility in time, such as the Shaafi'i school, have no objection to what you mentioned. They do not see any sin in postponing Hajj even if one is capable of performing it. As for those who consider it obligatory immediately, they are of the view that the crucial time is when people start going for Hajj. If someone possesses the means to perform Hajj during that time, it is incumbent upon them to promptly undertake the pilgrimage. If they spend the money before that time without the intention to evade the obligation of Hajj, then they are not blamed for that. However, if they spend the money to avoid the obligation of Hajj, it is considered a trick, and they risk sinning, as using tricks to evade religious duties is considered forbidden by many scholars.
As for your second question, it is recommended to resend it as a separate inquiry with additional clarification, as it appears to contain some ambiguity.
Allah knows best.
