Tally to Quickbooks Conversion

I am a Practicing Chartered Accountant and I am looking to onboard five of my clients into Quickbooks. I would like to convert five of my client's data for two years (roughly between some 2000 to 10000 vouchers per annum) into Quickbooks. I have a 30 day free trial license to quickbooks which I will share the credentials and once successfully converted, I shall subscribe to quickbooks and take this forward. Looking for people who can convert the data from tally to quickbooks through bulk data export.

Five Client data for two years to be exported from Tally and Trial Balance Should match for two years in Quickbooks.
