Greetings,
I have read Project Description & please provide me URL of your BigCommerce website, as one of my senior technical team lead already worked on BigCommerce, so we are very well aware of the structure of it.
Also, please send me the spreadsheet for our better understanding and estimate.
Our current bid is just a ballpark estimate but once you respond us, we can then negotiate it & finalize, as we are flexible in prices.
Look forward to hearing from you.
Regards,
YK
