Some well meant advice. You'd be wise to consider your competition and put yourself into perspective so you know where you stand in terms of quality compared to other builders. From there you can assess your position & price your cues accordingly. You are charging $900 for a very simple cue equipped with one high grade shaft. You are charging $300 for good shafts, and asking less for sub quality shafts. Your competition doesn't even offer sub quality shafts and for their top grade shafts they charge at most what you do for your mid grade shafts. By competition i'm referring to other builders who are doing work comparable to the pics you are showing of your work. I can only assume you are showing the typical or top end of your ability level. Nobody shows their junk in their sales pitch. So I can only assume what you have shown is a solid representation of your level. Correct me if that's wrong.
Given your pictures, knowledgeable buyers can quickly asses your level and place you in the hierarchy of cue builders. I'm not here to judge you & won't but I will hint at you that your pricing is not consistent with your position. Barry Szamboti, Dennis Searing, Richard Harris, Lauri Franklin, Ron Haley, etc. charge your rates for shafts. And they don't even offer sub quality products. They throw it away & only put out something they are proud to have their name attached to. Your top of the line shaft is their only shaft, their standard. And they don't advertise nor need to. Their cues have history, track records that speak volumes so they don't have to give sales pitches. Everybody who buys one is entrusting the general public's opinion, not the sales babbles of the builder. Point being, you might think about reassessing your approach & maybe take a more humbled path. It looks better in the eyes of buyers & if your product is as good as you think it is, then it'll give you more business than you can handle & you won't have to say a word.
One last thing is the sales babble. True or not, your claims give a scammer's stinch. Some folks will most certainly buy into it but you'll miss the big boat. You want the big boat. You need the big boat. Ask Eddie Wheat about missing the big boat because of his mouth. He swore he could prove his claims, too. Where is he now? Oh, you haven't heard of him? Enough said. He went nowhere real fast.
Let your work speak for you . It'll say volumes about you as well as their quality. If you want to talk cues, go to the cuemaker forums & get involved. I promise you'll learn something. Hopefully you can contribute something. But know it all self promotion is not a well succeeded tactic in the cue market. You are new & only have a couple of threads. Not a big deal. As badly as this one went, imagine how it'll be if you continue the same way. So again, just some friendly advice. Take it, or not. Time will reveal your worth regardless.
