House please I need candid advice for the ITA application to Canada.

I want to travel first and then move the rest of the family over because I currently have 5 million naira which should cover the proof of funds for only one person, plus logistics fees needed to travel for only one person.

NOW MY QUESTIONS:
1. In the application, should I apply as a single person, since I want to travel alone first? Won't this option bring up honestly issues latter when I want to start processing the papers for the rest of the family once I get to Canada?

2. If we are to apply as a family, can I be allowed to show proof of funds for only myself, since I am the only one traveling first or would I be still required to show proof of funds for 5 persons?

What is the best way to go about this please?

Thanks in advance for your prompt response.
