I already do several commercial clients every week - including costa coffee, a casino, a high street shoe shop, a restaurant and others - but now I want to get some big players like the high street banks, wetherspoons, fast food places and maybe some office blocks. I've already been in and spoken with these big chain retailers and they pretty much all say that i need to get hold of head office and apply to them, so thats what I've started doing. I've been emailing them with a pitch I've created. Has anyone on here got experience with securing these types of clients? If so do you have any advice? I know that most will already have window cleaners but at least if I make them aware of my details, then maybe when they need to switch they'll call me up.
