Hello and welcome!
Yes, by all means, take your time.
The most important thing to do to avoid blowing your budget too quickly (because, let's face it, it will happen eventually) is to define your game.
Cash? How many players, what are your stakes, what's your estimate of the largest amount of money on the table at the end of the night on your biggest night.
Tournament? How many players, what is your blind structure, do you allow rebuys and how much/how often, when and how to colour up.
Once you've locked down this info, the rest is easy peasy from there. I swear, you won't even notice the money flowing out of your bank account.
