Grow Internet sales for new start up business

Hi

We are manufacturers of brushed metal business cards. Please see our website - www.metallicdesign.uk. All our sales come through referrals.
We have not explored the internet as a sales platform and understand this has great potential.
One of our biggest reasons for refraining from exploring this option was due to not being able to supply demand. We have recently invested into new equipment which we envisage will give us capability to produce larger quantities.
Please let us know if you can help with the internet side of things. We know that nobody can guarantee exact figures on projected sales but we want a clear indication on what you can achieve for us. This will be backed up with evidence from your previous projects and you will be able to provide us this.
On another note - we are happy to discuss you becoming a partner for the business where your responsibility would be the sales and marketing.
Thank you and happy to take any questions.

Regards
Metallic Design
