I would keep it quiet until the first delivery to each new client. Once one delivery is in place and the client has quality, low cost bearings (I think they should be renamed bullings), they will tolerate a few calls and then do what I do and block the caller. I am quite brutal with the few cold-call vendors who get past my admin.

I don't mind trips for a while, that money wasn't doing anything for me anyway.

If nothing else it keeps me interested and entertained. (The thrill of the hunt and all that jazz)
