I need a speculative cover letter by the end of today

I am needing a speculative letter to be written by end of today. I am currently looking to target small wealth Management/ IFA firms who are not neccesarily advertising any positions. The letter doesnt need to be long, put bespoke, selling my experience, skills, include industry specific keywords and power words. I have supplied one company that i am targetting, all i need is someone to write a bespoke letter selling my skills and if possible finding out about the company, its key achievements, mission just so i have done my research and why would be a good fit. I will forward my CV - its currently working with jobs that are advertised, however, i much prefer to find a company that hasnt advertised, cutting out competition. I will also supply a job spec of the type of role i am looking for. Ill be honest, im not brilliant at selling myself on paper, as to the reason why i am looking for help.

The freelancer that works with me will receive my CV.

I have supplied below and typical job spec of the ideal role.

I ideally want the Cover letter to use cambridge english, makes us come across sophisticated. I have work with some of the UKs prestigious firms and i need the speculative cover letter to come across same way.

To make the job quicker, i will supply you with some key selling points which all you need to do is to rewrite onto the letter so i am selling myself to the company. You may not use them all, but please use any that you think best matches. Im sure you will have more experience and many feedback or required information to better help the letter to stand out, i will help.

Now the company i look to target is a company i used to work for, I am also targetting other similar firms as well to this one so i will use the spec letter that the freelancer writes for us and ill adapt to others.
