Cabrio roof replacement near Bournemouth/Southampton/Salisbury

My roof now definitely needs replacing. I'm on the border of Dorset, Wiltshire & Hampshire and can easily handle an hours drive to drop the car off and collect when finished. I've been told of a firm called Portchester Trimmers that could possibly replace the roof for me, if anyone has heard of them and their work I'd appreciate the heads up.

I'd be interested in details of any firms that people can vouch for in Bournemouth/Poole, Southampton/Portsmouth, towards Basingstoke, Winchester, Salisbury, or out towards Yeovil at a push.
