Once the BizSpark program ends for me is there a low cost solution for getting access to tools like Visual Studio?
I've seen before people talk about $300 or $400 annual subscriptions but I wasn't sure what that was for exactly.
If that entity can't get profitable in 3 years (enough to pay for msdn licenses) then it is probably a goner anyway. Time to start a new venture...
What is it that you are using the BizSpak program for?
Is it to build your product/solution?
If this is the case, then you are being too slow bringing your product to life... as Tim mentioned, this might indicate that this venture is already dead!
Can you explain a little more what is it that you're doing and what are the longer term plans?
Establish a new entity, transfer IP to new entity, outsource development to new entity, sign up for BizSpark with new entity, then repeat in 3 years.
You get to keep your Visual Studio licenses, and you must buy SPLA licenses (or the similar at that time) for your production servers. SPLA is not low cost, but then again, BizSpark is intended for startups wanting to become successful companies, not hobby projects.
