Hi,
While an affiliate, I also have all this issues, but with time and research it becomes easier to manage your team.
I also use a project management platform, but not Basecamp anymore. Recently I changed for a new one (Podio.com), much more appropriate to your own customization, since you can build your own app.
Give it a look, you will see the advantages, and also the support team is always available to heard suggestions from you, in order to improve the platform to your way.
Just my two cents 
Cheers,
