You had a company build your creation, great! Does it do everything like you want it to? Some questions you need to ask before your site gets popular. Can my site handle 50000 users at a time? Can a user input a SQL injection and hack your site? Are all the validations on the different forms checking out? Testing engineers try to break your site before customers tell the world. I also find issues with your site before the hackers do. Hire me to tell you about the problems before you start loosing customers.
After 20 years on the job, I learned that every developer don't know everything. Things that I do know, I know very well. When you hire me, you are hiring someone who builds projects from scratch. I learned that not all programmers write the same, nothing in the programming world is a quick fix. If you need something changed that is a quick fix, learn it yourself. Go on YouTube and learn it. The time it takes you to find a developer or a team is the same time a developer from YouTube has told you how to change it. The projects I take are projects that are very well detailed, all content are spelled out, and I know the look and feel of the site. After that, let me finish the project. Most projects do take 4 to 6 months to build.
