Rewarding Allied Resources

[Ashley Byington]

I wasn't quite sure where I should post this question. If it's already been asked and answered please point me to the right place!

How do you stay in touch and reward your allied resources?

At the real estate office that I manage we sell real estate for Buyer & Sellers, and we also have our own rentals that we manage.
We've built a team of professionals to help us out on a myriad of issues:
Plumbers, Electricians, General Contractors, Septic, etc. 

We are doing an end of the year lunch next week and inviting everyone. 

Any ideas for the rest of the year? 

Thanks!
