Thought of a plan and wondering if you guys think it would work, tbh recently I've been getting impostor syndrome on sales calls even though I have got really good results for my clients previously. So I was thinking, what if I just offered to take on 10 free trial clients for one month, get them really good results and ask for a testimonial in return. That way I get 10 testimonials and/or some of them stay as paying clients which I can use as referrals to close more clients. I feel like this would just make it a lot easier for me to sell and I can prove myself to each client before getting paid, since I know I can. Do you guys think this is a good idea? Or should I just charge them right upfront?
