Migrating data into Xero

I need help entering data into Xero for my newly formed company (incorporated in May 2019). The bulk of transactions come from the expense reimbursements made by one of my clients (they use software called Expensify and I was able to pull an excel report from there) - I'll need help with entering data, pulling expense receipts from that report and attaching them into Xero. Once I'm caught up with historic transaction, I'd need help with keeping books up to date, payroll (one employee) and year-end tax filings (corporate and self-assessment). I'm looking for a long-term business relationship with potential for some additional ongoing work if all goes well.
