Can you help me ?

I have a Master's degree in Economics and Business Management and I am very interested in improving my work experience. I am enterprising and keen to learn new skills.

I study and speak English mostly for professional requirements, rather than for my own passion. I am available to relocate to the UK immediately.
I look forward to hearing from you.

Yours sincerely,

Carlo.

Ciao, Carlo! Questo paragrafo mi sembra di essere ben scritto e professionale. Per cui motivo lo usi? Forse una domanda per un posto in un sindicato? 

L'inglese sotto qua e quasi-perfetto. Ti darei consigli solo sul contento, non sulla grammatica. Forse, dopo di dire "I am enterprising and keen to learn new skills," devi aggiungere un esempio concreto, tipo... "For example, I held a position at Company XYZ where I...", or "I held an internship where I was required to..."

Non direi che non ti interessa l'englese per motivi personali. Anche se e' vero che hai imparato l'inglese solo per lavoro enon per la sua propria passione, non vorresti sembrare disimpegnato o senza entusiasmo. Penso che sia meglio dire semplicemente, "Through my work experience, I have gained familiarity with the English language," or, "For my position at Company XYZ, I communicated with many customers in English..."ecc.

I hope this helps! Let me know if you have any questions about what I mean.
