I am a Handyman / Home remodeling for over 25 years. I lived in 6 different states since graduating high school. Fortunately I am able to easily relocate. I have spent a life time buying tools for all the different projects I do. 5 years ago the economy was terrible. After spending some time looking for the right estimating app on line I decided to make my own, not knowing the full extent of the idea. After using YouTube to learn Excel I found some help online. During the first 4 years many updates and changes have taken place in the development. I have found a young man in the Philippians that knows how to code. We are in the final stages with the estimator as an add-in in Excel. We are creating a survey for 10K email address to do some more digging on their likes and dislikes of the apps they may be using. After the completion of creating the add-in we will use is as as the working model to build the app. Now with the block chain I am looking to see if there is anything here I can implement into the estimator to keep it up to date.
