What I need for a triathlon

So I am new to triathlons, I have been running for 1 year now I can do 5k in 27:00 and longest i run was 11k in 1:10:00, I know how to use a bike but I have not bike for a long distance, and my my swimming skills are zero.

Recently I started watching many people do triathlons and I decided that I want to one one myself specifically Ironman I know that is a big goal, I have no time goal in mind I just want to finish it and I don’t know where to start so for experienced people can you let me know what bike should I use and all equipments I need for training day and for the race, also I have 1 year for training and I am broke so put that in your mind

So basically:

What bike should I use (not expensive pls)? What Brand of gel should I use ? Which swimming suit I buy ? How many km to run, bike , swim a week

And all others questions regarding this topic

Answering this questions would be so helpful ?
