The primary design meeting some would disagree is an absolutely vital element of the whole design process. The primary design assembly is where the designer gets a texture of the client who they really are and what they are most highly looking for in their website. The mock up could be opening up a figurative can of worms if the client doesn't like it initial this could set you off on a course to destruction with the client left doubtful of your abilities. This in turn could render the mock-up not so much as a deal clincher but rather a deal breaker. Be cearful with cheap web design.
Some web developers are of the brand that by presenting speculative design that they are somehow short-changing the client by them omitted gout on that all vital initial design meeting. One mistaken move in the speculative design is it the wrong color or a miss placed imaged could turn the client off completely from the whole project. When it comes to websites the design is not just all about the aesthetics, the aims and objectives of the business have to be considered, who is there target market? Branding? It's so much more than what a speculative design can offer.
Another part in the design process where cheap web design can be less than obliging is that they have the possibility to cheapen the service. If the speculative design is accessible free then it may set the client to thinking well if they can do this for free then the full service shouldn't be that posh?
You may want to know what we should do then. You can showcase your portfolio which is an excellent way to show your customer what you can do but they won't be turned off if they don't like it as it's not connected instantly to their project. Moreover, in the advantage of the trendy that is work they have already done and aided from, not work they are spending hours on for theoretically no reward.
