Business Partnership Proposal Review + Business Partnerships Creation

As part of my new marketing campaign, I am looking to establish mutually beneficial business relationships with both small and large companies that wish to join me in my continued effort to encourage young people to learn music.
My website address is www[dot]kensingtonpianolessons[dot]com.

I created a short business partnership proposal, which I would like to send to a list of approximately 20 companies that can potentially be interested in working with me.

I am looking for a Marketing / Sales expert who can help me with the following:

1. Reviewing and improving the partnership proposal I have created;
2. Finding out who the decision makers in those companies are;
3. Emailing the proposal to them;
4. Following up with a call to see if they would be interested in working with me. If they request a meeting – I would be happy to do that.
5. Taking any other necessary steps that can lead to creating a business relationship.

I am looking for a native English speaker with appropriate writing skills, who is based in the United Kingdom.

I would be grateful, if, when submitting your proposal, you could include the following information:

1. What would be your approach to the project? What is your proposed plan of action?
2. What is the timeframe?
3. What are your fees?
4. When are you available to start?
5. I’d be grateful if you could also write a paragraph about yourself. What is your background? Who are your clients? Do you have any recommendations?
6. How will the success of the project be evaluated?
7. If you are based in London, will you be available for a meeting?

Thank you for your time. I look forward to hearing from you.
