When I was starting out I told people the truth and all about my plans and my experience with my own children including many years of crafting in Guiding/Scouting. I got my CPR/first aid right away but I admit I started with my rates lower and told people that I appreciated that they were taking a chance on a new HDCP but I would be reliable and responsible and loyal and would never let them down. Find your strengths and advertise them. Mine were these plus the fact that my children are grown so I can give all my attention to the daycare children. Yours will be different but figure that out and find your niche.
You don't want to be desperate, but you do have to plan out a daily routine and the kind of daycare your want to run. I had no clue when I started and there will always be a special place in my heart for those people who were my first great clients who stayed with me so I could learn a lot from them and about running a daycare through practical experience.
