Netherlands over Ireland? Not really a specific reason. In my view, Ireland will have a hard time soon, due to Brexit. Netherlands is extremely (too) stable, they all talk English, is an escape for lots of big corps that fled London, seems to be #4 on the list of off shore countries(?) and it has a very liberal stance on many things, except for spitting on the ground and tax-evasion.
With such a low number of transaction, you won't need an accountant. However, you will have to do a bookkeeping and fill in the tax-form each year. Bookkeeping is done through a program that cost you 15 euro a month and it spits out the correct calculations for the tax man. Best thing to do is contact an accountant for a quick setup or simply buy an aged company. You can have these from young ones for 5K to aged co's for 25K. Some of them with deductible losses on board and some with big agio's waiting to be monetized. It depends on what you're ready to pay for it.
Turnover as an IoR can be low, or super high. Cashflow volume is important for banks.
