We're a B2B video services company that is nearly 100% inbound lead driven. As we grow, it's not enough. Our pricing is 10-20k, so we really only need 2-3 more deals a month. We hired an SDR to prospect and schedule meetings for our Account Exec (who's amazing at closing). The SDR just didn't produce. We are trying ads but haven't cracked the advertising landscape. We've just started investing in inbound/content marketing and need a few months there to see the results. We're working on a referral system to get more from our existing clients. We're avoiding the cost of hiring a baller biz dev guy right now. I feel this is our next best try. Or do you recommend something else?
