You came to the right place.   You will be inundated with replies when they wake up in the states LOL!
I'm in Spain. It all depends what you need.

Hi there,

Hi, you can contact me through https://datafounders.com - we do quickbase and also integrate it through APIs and javascript with wordpress sites and other services.

Please let me know a bit of your scope and I can quote you a rate. 
Most of us here are very qualified for most quickbase tasks. It's a good community. 

Feel free to contact me using the information in my profile:
