Option #1: You can suggest that the desired calculator be added to my calculator store where you can license it for $15 -- with no guarantees as to if and when it will be added. The more I feel the calculator will be of interest to my other customers, and the more detailed the specifications, the more likely the calculator will be created and added to the store.

Option #2: You can request that the calculator be made exclusively for you (calculator won't be made available to my other customers), in which case the cost typically runs between $35.00US and $225.00US -- depending on the complexity involved and the quality of the specifications. A firm price quote and forecasted turn-around time will be sent to you once I am provided with the finalized, exact specifications.

Format Option #1: A final working copy of the calculator in an Excel (or OpenOffice.org Calc) spreadsheet format -- free of locked cells, hidden formulas or dependent macros.

Format Option #2: A line-by-line description of the calculator's inputs, outputs, and formulas, along with two real-life sets of inputs and their corresponding expected outputs.

If you would like to suggest a calculator for the store, or would like a quote on a custom solution, please complete and submit the form below.

If you are interested in a custom solution, please read the following disclaimers before submitting the form:

• Before I can begin work on a custom solution, a deposit of 50% of the accepted quote is required. The balance of the accepted quote will be due once you are completely satisfied with the finished calculator. I accept payments via PayPal, 2Checkout.com or paper check via US Mail.
  
  
• I create calculators using a client-side programming language (javascript, compiled and run in the user's web browser), which means the calculators I create will not be able to store or email information, and will not be operational for users who have javascript disabled in their web browser. It also means that the code for the installed calculator can be copied from your website. Printer friendly versions of the results are included as pop-ups, and may not work for web browsers with pop-up blockers or corrupted registry files (common in IE 7, 8, & 9). Furthermore, any interactive charts or graphs you would like included will be provided via an embedded Google Chart -- with no guarantees that Google will continue to support the embedded chart.
  
  
• It is extremely important that the specifications I'm provided with are complete and final, as any revisions needed due to changes to the original specifications will be billed at $35 per hour - on top of the accepted original quote.
  
  
• I cannot not be held responsible for any installation problems related to installer inexperience, HTML editors and/or website builder software. Therefore, if you think there's a chance you may have trouble installing the finished calculator, please make sure you can get the trial installation installed and working properly. If you are unable to install the finished calculator you will still be responsible for paying for its creation.
  
  
• The final design of the calculator's user interface will be up to you. I will do my best to design the user interface to match the design of your site (if provided with a url of the site or a template, and any images you would like incorporated), and from there you will be free to alter the HTML (colors, fonts, layout, dimensions, etc.) as you see fit.
