I typically estimate cost based upon a single price for the entire project. I can work 'by the hour' in my pricing, but prefer not to except in certain circumstances. I can also itemize individual components so that a client understands where the costs of the project is weighted.
A small web site of only a few pages generally runs approximately $100.00 per page, but this can be a misleading way to understand my pricing. Adding devices such as interactive contact pages, click-to-purchase buttons, or other extra site tools can add additional costs. Likewise, reducing elements can drop the cost down.
Magazine and Newsletter Design: I strive to provide a 'per page' cost, with a total price number so that the client knows what our target cost is before we even start.
Logo Design: Costs here are provided with an eye toward three revision stages as the initial logo design that is approved by the client is refined through three 'correction' stages. Generally, further changes desired by client beyond three revisions typically incur additional costs.
Special SEO Services: Gathering information to create a complete picture of a web sites health vis-a-vis search engines requires time and the use of special research tools. Comparing information between Google Analytics, web site logs, and SEO tools like "SEM Rush" and "SERP tracker" means amassing data and coordinating it with spread sheet analysis. Pricing depends upon the depth of information desired, and the amount of ongoing refinement to a site with an eye toward boosting specific site pages over their current page rank status.
I use an online invoicing system that allows a client to pay using a credit card, debit or charge card. Also, payments can be made by check or money order.
With a new client, I will usually ask for a deposit before work begins. With existing client accounts, I bill according to the length of a project, typically month to month.
If desired, payments can be made over an agreed upon time.
