Hello,
I am writing to propose that you choose me to help you express your love to Josephine.
I am a native English speaker, and have had a love of reading and writing since adolescence. I am now an adult working on my second university degree, but I still write for fun, relaxation, and emotional health. Needless to say, I have also been in love, and felt an immediate sense of understanding when I stumbled across your description of your project.
I would be interested to hear more about what you are seeking in a letter, or statement, for Josephine.
Please get in touch with me, at your earliest convenience. I wish you all the best.
Sincerely,
Alexis
