[General] Please help me write these letters- I am not doing a good job

[soleinspired]

Hello Everyone,

I am new here but I pray there is someone here that can help me. I am in the process of coordinating a cake convention. I am at the point where I need to start inviting guest such as celebrities to give demonstrations and classes, people to judge the competitions, and sponsors that I hope to sponsor the event. I need to write three separate letters but I am at a lost for words.

To the celeb guest:

Hello

My name is -----. I am happy to inform you that the first semi annual cake competition will be held in Baltimore at ----- on August 13, 2009. I am writing to request your attendance at this event. I would like for you to come and either give a demonstration as well as judge a competion. It would be a great honor to have you at this event. I understand you have a very busy schedule but you are one of the reasons why so many of us decided to go into this business and it would be great if you could attend to help kick off what is going to be a great event. I understand that you may have certain requirements and/or expenses that would need to be covered for you to attend this event. If you are willing to attend please forward me all information and requirements so that I may hold this date with you. Thank you for your consideration.


P.S.

Feel free to check out the website at www.-------- for more information on the event.

Sincerly

With the letter to the sponsors and vendors I wouldn't even know where to start. I already figured out what packes to offer and how to format it. I have no idea how to write the letter to make it look attractive so that they would want to sponsor the event. Should it be something that is long and more detailed? or should it be straight to the point ( This is event is going to be huge! First of it's kind in this city and you need to jump on board because the earning potential for your company would be more then benefitial to you.)

I obviously don't know what i'm talking about. It is embarassing how horrible I am at writing letters. For some reason when it comes to writing letters it is impossible for me to get what I want to say down on paper.

Would someone please help me. I have a deadline of August 1st to know who's coming, who's not and etc. and if I can't get these letters out then I guess i'm screwed.

Thank you all in advance. I really appreciate it.
