Let's say for example we have 30k we want to reinvest into our startup company, and the purpose of the budget is to make sure they help us reach our goals for summer 2017. How do we go about building those out so they are successful and not just like "well we will spend money here, here and here and hope for the best"?
This is highly dependent on many factors. Clarify your question with the following specifics + likely someone can assist you. The more specific your question, the more specific + useful answers you'll receive.
1) You specific goals + how they're measured.
For example, there's a big difference between having a large customer list + an profitable customer list.
2) You customer demographics.
Male/Female. Chronological age. Etc...
3) Your client psychographics.
Why they buy, which surfaces the problem you're solving for them.
4) Your product/service/info.
What you're selling + it's price point + it's repeat purchase cycle.
You might be surprised at the massive profit you can generate by simply attending Meetup Groups yourself + giving a correct (benefit centric) introduction.
Then spending you $30K hiring good looking people to do the same in many Meetups in your area.
You can also use this same approach with any speaking circuit type system, like WordCamp or any industry trade show.
In general, if you require investing huge amounts of money to make money, scaling can be complex.
If you can spend near $0 + produce massive profit, then scaling becomes smooth + easy.
I've done it both ways.
I suggest you stick with smooth + easy.
