If you want to invest some money in serious stuff, you need to consider MSDN. Most of Microsoft products sold through eBay and other online platforms are made for startups but they have the same features as retail codes. These products include but are not limited to:
Windows 7, 8, 8.1, 10 and their editions.
Office 2007, 2010, 2011 (Mac only) 2013, 2016
Project Professional 2010, 2013 and 2016
Visio 2010, 2013 and 2016
Virtual Server and much more
We're talking about hundreds and hundreds of product keys, litterally. Along with this, you will also get $150 every month that you will be able to use with VPSs, websites, CDNs, other kind of servers and much more. You would be able to use this to run an enterprise-like website at a REALLY low cost.
