Hi!
It would be much better if you share the URL where this site could be observed and examined how does it manifest itself on the front end as a starting point for assessing what might be involved in this.
NB: Until further details are forwarded and a proper assessment has been made the bid parameters - both cost and time are to be considered rough estimate and not binding, as those can change based on the results from the assessment.
Regards,
Dobri
