What are some way I can become a good networker? Meaning how can I find good contractors, good lenders, good law firms and so on? Also what are some tips to not spending more than I profit on these choices? Will people work with you more than once? Will it be a one and done deal? Also what can I do to better understand how these all correlate and work so I'm not spending money improperly and only spending money for the good?
