I need a sponsor/sponsor's to help me purchase a street bicycle to race in the Los Angeles bike marathon?

im 17 years old and i need a sponsor to help me purchase a giant street bicycle so i can be in the March second bicycle race in Los Angeles ...
i currently have a trek 6000 and i have no idea how to sell it but i think its only worth like $400 the bike i am trying to get cost around $600-$700.

Can anyone help me?

When I first started racing, I went to school, had a paper route, cut lawns, and raked leaves on top of training which got me to the Olympic tryouts.

This was 1975 and my bike cost me $867.00- it took almost a whole year and all my savings, plus my parents nearly killed me.

So, instead of trying to beg, keep your eye on what you want to do and work towards it.

EDIT: If you are interested, my first racing bike was a Zeus Cronos. Burgundy and gold, with black anodized parts that were then machined and drilled for lightness. First large scale use of titanium in bike parts (though the frame was, er, is steel). I still have it.

Please tell us why you deserve a sponsor?

Edit:
My 1st real road race bike was a mid '70s Raleigh Road Ace with a 531 db frame and sew ups. It's cost me about $380 which is about $1000 in today's $$$. I worked in a bike shop for $2 an hour, part time after school and weekends. I worked a long time to buy it, and oh how proud I was when I brought it home. Now you can buy a better bike for $700 and anyone can make about $7 an hour.

Bikes are cheaper than ever indexed to inflation. I had to work 190 hours (no taxes) to buy it. Now it's 100 hours, what a deal!

I am sorry, but if you haven't been paying attention to the news, we are entering a recession. That means money that was scarce to begin with, will evaporate. If you prove yourself to a sponsor by selling them on how much exposure you will give them -- then you get a sponsor. There is no sponsor list. Every sponsor has to be earned.

I was like mirage (that's weird!) in 1970, at 15 I took $180.00 of my hard earned dollars to the only import bike shop in town and bought a Gitane TDF. For reference, a new 1970 Mustang cost half the price of a 2008 Madone 6.9 Pro. Money has changed -- the effort and desire has not.

You need more effort.

Edit: mirage, I still have mine too. It's Reynolds 531 and tubulars. So you did have early use of Drillium after all?

I can help you. Ride your Trek 6000. You might even run down to your local bike shop and buy a set of 26x1.5 slick tires. I've seen them on sale for under $10 each at Performance. That will help you be more competitive.

Problem solved.
