I'm currently redesigning my financial blog and wanted to integrate some useful tools for my readers. These financial tools are calculators for: compound interest, mortgage, and retirement. The calculator(s) will first be designed an then programmed, so that they are consistent with the look of the site. What I'm looking for, can be found here: Compound Interest Calculator Mortgage Calculator Retirement Calculator This is a paying gig and I would like to get three things from interested parties: 1) Cost estimate 2) Time frame (turnaround) 3) Guarantee that it will integrate with Wordpress Payment will be via Paypal and will be made once the job is completed and tested.
