You asked what options are best for your scenario.

I don't know what you are considering as your VM hosting provider for those 
particular sizes. We use Digital Ocean.

Their $10/month plan should suffice you. However, if you plan on expanding 
your inventory or having excessively high circulation rates, go with a 
higher plan.

I always recommend at least 1GB (=1024MB) RAM. This can impact the speed of 
your reindexes. 20GB disk space is functional for a small test system, but 
more is always better.

Please also consider the underlying VM technology involved. The other day 
someone had issues with their VM, and it turned out they had OpenVM and the 
node they had in question was a problematic one (probably because all the 
new people keep getting auto assigned there and overloading it). OpenVM 
providers tend to also be cheaper. A price difference that could mean the 
difference between an upgrade headache and upgrade ease.

GPML,
