Tax advice required on Share ownership in Startup

A colleague and I would like some tax advice on share ownership in a new UK startup company.

In particular I am receiving a certain number of shares from the owner in return for my work. Currently the agreement is that a certain percentage of my shares will be \"vested\" after Year 1, and a certain amount after Year 2 for example. I have aksed for shares rather than share options.

I need to fully understand the tax implications of both and how best to structure my share ownership.

Can you please quote for a 1 hour conference call with me and my colleague to discuss what options and tax implications there are, and also to provide a written summary (1 page) of your recommendation after the call.

Please only quote if you are an expert in UK Tax in particular with respect to ownership of shares and share options.
