Filling a UK VAT return for a start-up with 12 transactions during the first quarter, all outside the UK

I am looking for a professional to fill in a UK VAT return for my start-up. During the first quarter of this year, I've made 2 sales and 10 purchases, all outside the UK with a total value of £6200. I have all the necessary receipts and documentation, and most of the transactions have been subject to VAT. Non off them are subject to UK VAT. At least one sale is subject to the reverse charge rule. Therefore, I need someone experienced who can accurately fill in the VAT return form which I would like to file myself. Knowledge about European VAT rules is needed. If you believe you could help me with this project, please do not hesitate to contact me. Thank you!
