Hi, how are you? My name is Igor and I'm managing a team of expert developers with large experience in various areas including complex client/server system with backend running in cloud (or in company server) and multiplatform client (web, windows, android, iOS, linux).
I've reviewed sites you've posted as template and have a few questions, namely about multimedia content, videos, presentations, samples, do you already have them prepared or are you working on them or do you need help in that area. As for development itself, it is not a easy or fast but it is straightworward, with carefel initial planning and task allocation we can get to production in several months.
