Extra notes: Most of our translation work has been on a freelance basis and feel that now is the right time to have our own website and marketing/SEO etc.

As we want to test the water so to speak, a cost effective website with the flexibility to grow through future upgrades would be advantageous.

I would like further discussion to be during private negotiation and look forward to hearing from interested parties.
