Need help with valuation case study

I'm trying to complete a valuation case study and running into some issues. I was given an asset management firm with 100 M AUM, management fees of 1%, EBITDA margins of 25%, and given the firm will grow AUM by 15% each year. No D/A or Debt. Should I be trying to create an IS/BS/CF statement from this info? As of now I just did valuation using comps/precedent transactions that I found in research reports online. My comps valuation is nearly half of the DCF valuation. Can I even use a DCF valuation for this case? I know you aren't supposed to use DCF for FIG but I don't really have much information about the given company. Any help is appreciated. Would be willing to pay someone to chat with me over skype or something and help me with this.
