It's excellent you are taking this seriously.
Group Pujas are just a thing. Real practitioners practice four times a day. It isn't possible to have a dozen or more people to come to the temple four times a day every day.
The usual way to practice is by yourself after receiving initiation and instructions. Occasionally visiting your guru to share your process or lack of it and ask questions and receive advice. This is method taught in the Songs of Milarepa, the Stories of the Eighty Four Mahasiddha, and others, such as this verse from Tsongkhapa's Three Principles of the Path, which was a letter to one of his disciples:
(14) When you have understood the points of these three
Principal aspects of the path [Renunciation and the two Bodhicittas], as they are,
Rely on solitude and,
by generating the power of joyful perseverance,
Quickly realize, my son, your immemorial goal.
On that theme: rather than memorizing a bunch of words, isn't it better to memorize the meaning? Rather than memorizing the meaning, isn't it better to understand the meaning? Rather than understanding the meaning, isn't it better to live the meaning?
It is essential
for you to only
receive initiation from people you will respect for life. So meet and learn the character of possible Gurus first. Then request initiation and instructions.
I hope you attain Enlightenment quickly.
