You'd be crazy to sell anything below cost, and suicidal to approach selling financial advice on the basis that cheapest is best, or that it will win you any customers. This has been tried and failed by many others ahead of you.
Custmers like these have no respect for you as an advisor, except that you've given them a below cost deal. As soon as a cheaper more cheerful offer is made these types desert the ship, understandably so since they represent the skinflint population.
You'd be best advised to move upmarket, and build with solid referrals from people you've impressed with skill, attention, and service. These types recognise that hiring someone on the basis of cheapest quote is plain dumb in many cases, from house construction to professional services like legal, taxation, and financial advice.
