Boekhouder gezocht voor startende BV

I have just started up a company, and need help with the omzetblasting aangifte..
My company is situated in Amsterdam.
I am the director in my company (and single employee as of now) who has
a contract with an Indian company to sell engineering drawings (technische
tekeningen) and also 3D rendering / modelling etc using latest ICT tools and
software.

I would like to use for more than only currently so it will NOT be a on time thing, but repeating.
With Regards / Met vriendelijke groet,
