Here is the problem. You are not continue consulting with us on your revised plan if there is one.
You asked us how to get started, then you didn't tell us anything about what your plan is before you seem to ready to bail. When i asked, you said 30 gallon for blood parrot.
A 30 gallon tank is only the bare minimal for just one Blood Parrot. Each additional needs minimal 10 more gallons of water. That's why I said earlier you need 100+ gallon for just a few of them. Your plan isn't going to work well unless you really plan to have just one blood parrot, and that is not a good set up since blood parrot are very shy and it will work better if there are a few more of them.
There is also other concerns. Including filtration, heater, air pump, water conditioner, as well as food, feeding routine, and tank maintenance. On the top of that, there is also aquarium nitrogen cycle. I know there is a lot to chew, but everyone who is seriously going to get fish has to go through all this learning curve or there will be dead fish soon.
