I'm not sure if this is the correct category but I need a little advice.

I would like to sell shares in an existing private company, the shareholder's agreement states that I must present them to existing shareholders first but the directors have requested (suggested) I find a private buyer and agree on a price and then offer them to the existing shareholders, trying to slow the process down.

I'm sure they have suggested this because they feel I won't find a buyer in this current climate.

My question is what information am I able to request from the company in order to facilitate a private sale?

I will need to give any prospective buyer information.

Also can anyone suggest any sites where selling shares in a private company may be possible?

Thank you for any help and advice in advance.
