Generally - you do not have tax-exempt status - all proceeds should be reported as your income. You may deduct all your expenses - so eventually you likely will not have any taxable income - but you still need to report both - income and expenses.
Unfortunately - as you do not have a status of charitable organization - any contribution (or payment for service) may not be deductible. You may provide a receipt, but you may not state on the receipt that this payment is deductible.
You may want to review IRS Publication 526, Charitable Contributions - http://www.irs.gov/pub/irs-pdf/p526.pdf for details or additional information.
Please let me know if any clarification needed.
