Need a local Brazilian to help with a business trip

Hello, Thank you for your help. We plan to make a trip to Brazil to find new partners and thus need: 1) A formal business invitation letter; please take a look at the attached file and you are welcome to make any necessary alteration but it should contain the necessary info of the contact person (probably, you or anybody else suitable), telephone number, CNPJ and others required by the Brazilian law. 2) Your reasonable requirement of the fee for the translation/interpretation between English and Portuguese per week or per month. We may require you to work continuously with us for at least one week or even one month. 3) Your location. We are very likely to visit Sao Paulo and the surrounding areas and we'll cover your travel fees with us. Please first take into consideration of the invitation letter here. After that, we are happy to go on cooperating with you in the following steps of the translation and local arrangement. It is a long-term work and hope to work with you as a good friend. Thank you and look forward to cooperating with you!
