Dear Sir/ Madam,
My name is Kevin from HeliosTeam. Have done with a project with OpenCv and BeagleBone Black. I am sure about our ability with your problem.
My team is interested in this project as it is exactly within our scope of expertise: We are an 3 years in embedded, mobile, server and programming group. We are located in Hochiminh city, Vietnam - where most of the high quality software in the world is being produced.
I understand that you might just look for a low cost product now. With your listed budget and the kind of requirements, we can only expect some quick work probably from part-time freelancers. It may serve well as a demo purpose. However, if you are really serious about software and determined to have a genuine piece which can serve several hundreds OR thousands of users concurrently, having strong code-base and smart UI with high expandability, or you simply need a professional IT team to back and run your app behind your business, please consider hiring HELIOS TEAM.
We also offer 3-months free support after handover, and then charge a small fee of $10/ hour for extra works.
Best wishes,
Kevin.
