Assist me with Bulk Marketing

I have the names of 100 companies I'd like to target in email or telephone. Ideally, first stop would be email and then I'd follow up by telephone. The numbers of many of these companies, like [login to view URL] and [login to view URL] are hidden: I've tried Google, their websites and 192.com. When they are revealed, such as with [login to view URL], individual emails are not handed out. Is there a way round this? My LinkedIn Inmail allowance is too limited as I'd like to mail the whole lot within a month. Would you be able to do the detective work on the contacts?
