Here's how I go about it (being a project manager I do this for a living)...
1. Prioritize your hobbies - which one is your absolute passion you couldn't live without. Put each one in a column. Column A would be #1, B would be #2, and so on.
2. Under each column put your needs under each hobby and prioritize them as you see fit. Put the cost of each next to it.
Your number one priority for purchase should be in column A2 (assuming A1 = Bowhunting). #2 priority is A3 and so on. At some point you'll get to the point in the A column where items in the B column will be higher priority. Start tackling the B column. Or you can take the approach of all hobbies being equal and attack Row 2, left to right.
Additionally, if there are items you don't use or hobbies you don't care as much about, start selling things off to increase your budget.
Keep in mind, it's only as expensive as you want to make it
