Dear client,
ReactJS is definitely the way to go. I personally have been working on-and-off with Ruby on Rails since 2007, more recently Meteor JS and now I am working with React JS. So I hope I can provide you with what you are looking for.
In terms of your requirements, could you explain a little more about the project, the other technologies you use, the possible duration of the work, the number of hours per week required, etc. Where are you based and are you a team of remote working freelancers?
In terms of myself, I am available to begin work with you immediately, however, I am actually 5 hours ahead of EST. I'm a english guy living in Portugal. I hope the extra hour would not be an issue for you. Also, I am a very hardworking person, I love technology and what we can do with it, and I have also worked on a StartUp organisation in the past, which I prefer.
Anyway, I really look forward to hearing from you and getting to understand your project.
Many thanks,
Daren
