Event Investor for Concert Series

I'm looking for an investor to provide financial backing for a series of upcoming concerts. The concerts have already gone on sale with 2,500 tickets of a required 4,800 already sold. However I’m seeking an investment for working capital to fulfill early deposits and festival site setup ahead of the late May shows. My business is focused on event planning in the music industry, and the concerts will highlight pop and dance genres for a diversified audience. I'm also planning to organize concerts for charitable causes. In return I’m offering a 50% interest deal to paid paid shortly after the shows happen (ie £70,000 investment - £105,000 returned). An ongoing working relationship is an option if all parties are happy working together. Ideal Characteristics: - Experience investing in event planning initiatives or within the music industry - Understanding of the pop and dance music markets - Interest in supporting philanthropic endeavors through the arts - Interest in helping independent event business thrive Please submit your proposal along with any relevant experiences you've had in this field.
