The skills needed list is not a list of "all required" skills. We just added a list that of items that separately would indicate you may be a good fit for the project. It is pretty clear to us that it will probably impossible and possibly not that useful if someone had all of these skills together. As you will guess from reading further: curiosity in cloud in general, hands on skills in system administration, scripting, programming, networking, server set up, installation, configuration or any combination of that wold be useful. The list of skills (out of the allowed on UpWork) is the closest of how we could have described that.
The long term budget limit of $50,000 is only indicative of long term budget. You will need to set a proposal amount for the small short-term project indicated below. Please, pay attention to this detail.
This may not be a very detailed description of the long-term ongoing project and may concentrate on the short-term stages that we need someone involved with.
