I currently use BigCommerce. Very happy with it, it's lightning quick and does more or less everything I want.
I don't want to move, but I've exceeded their sales limit and my costs have gone from $109 a month to $399 a month.
So I'm considering other solutions. I've used Woo before, and didn't really have an issue with it, but have no idea what spec a server I would need to self-host. I've never used Opencart. I prefer, if possible, to work with Windows systems (don't yell at me), but I'll work with Unix if I have to, although I would need help configuring it to make sure all security holes are patched.
What sort of cost would I be looking at to replicate my current site in Woo/Open/AN Other system? And what about ongoing costs, besides the server?
Trying to figure out if it's worthwhile, or whether I just swallow the cost increases. I don't want this to crop up again when and if I breach their next sales threshold.
