Omni, omni, omni! I like to read things several times to know what I'm signing myself up for. This is only my second bid, and therefore I will understand your reluctance if you do not think I'm the right person for the job.
It sounds like an issue that is well within my capabilities to fix! I have had a reasonably large amount of experience working with e-commerce businesses and WordPress, particularly troubleshooting and problem solving!
If you are not satisfied with my work, I am more than happy to refund you entirely.
Thanks for reading my bid!
