bay tiling

Hi all, I need your help. We are looking to getting our front bay tiles replaced and re-sealed etc.. Some leaks in the past and want to make it right. We have been quoted £1500 to do this. Is this correct? It seems excessive but I am a complete novice. thanks

Retiling a vertical bay with plain tiles, how much is a reasonable minimum overhang for the eaves tiles over the wood sill at the bottom of the tiled section? The way the battens are now, the overhang is only 1cm Thanks
