(Paid) Help taking sketch and developing an app

Have put together the Open Garden boards with an Arduino Uno and included an 8 channel SSR, looking to take this sketch and develop an app (using Blynk??) Let's discuss options and costs.

would be nice if you explain what a "mechanical" solid state relay is.....

Sorry, I'm very new to this...an 8 channel solid state relay is what it should have read. Ive updated the post.
