Haha great post Steven & congrats on your first deal!
I've been in the business since 2017 and have closed on over 1 Million in assignment fees since then.
My best advice is the following: Dont rush to scale your business, one HUGE mistake I see guys make after their first deal is to hire acquisition managers, get an office, buy a bunch of expensive systems and boom their business is in serious trouble. Why? Because they didn't have a predictable business with consistent lead flow (No lead flow = No Closings)
For now keep your overhead low - keep doing what your doing and study your KPIs, keep track of what marketing works and what doesn't, gradually invest a bit more into your marketing channels and have reserves for yourself (expect dry weeks/months with no closings). When you do decide to make your first hire, I recommend it be a Virtual Assistant, have him/her do all the admin tasks that are time consuming. Once you have a good grasp of what marketing channels give you the best return & you have closed a few more deals then I'd start looking into further hiring and scaling your operation.
Hope that helps.
