That's not a business plan...it's a plan for failing.
You need to start with a market survey - what is selling and at what price. Not what you WANT it to be.
then you need to figure out what you can bring that is different, better, unique.
Now, what gear will that take? CAN you get it in bits and pieces or not? (one speaker.. per month..no.)
Now you have a product, production (gear, music) and a price point - so on to marketing plan.
If in your research it shows that it costs $50 to get a gig, and you want 10 gigs then maybe you can budget $500. BUT it depends..you have no WOM, no reviews, no name recognition - you will spend more, or take longer, or get fewer gigs because of that. YOu have to factor that in to your plan.
So when it's all done you figure you need $7k in gear and 3k in marketing - $10,000 puts you in business. that's CHEAP. You can uber with out a $25,000 car. OMG, 10k! you say? Well, do you believe you'll succeed or not? If not..don't waste your time and money. If you DO believe you'll success then go get a low or no interest credit card and do it right.
You're investing in a BUSINESS, and in yourself. Figure the 7k will take 3 years to pay off, so $200 a month. the marketing is onging. If you can't get ennough gigs to cover the $200 monthly nut then well, it's not a business but a dream.
You need to treat the DJ business as, well a BUSINESS. Separate money, bank accounts, keep books, etc.
YOu need to be willing and ABLE to take risks - I'm doing a bridal show tomorrow, cost was $325 plus a door prize, plus I"m paying my assistant to be there, plus handouts (this time I printed them, but needed toner and 'fancy' paper - $80). No clue if I'll book a dime's worth of business. Risk.
And WTH is your 'out the door' cost anyway?
I did a school dance tonight..3 hours plus about 3 hours of setup/teardown and 1/2 hour driving and some prep time. I own all the gear and lights..had gas in the tank. Got $240. Doing a MS dance at the same place next month, a whopping $190 for those 3 hours. ZERO marketing costs. Hope to get the prom now. That will pay more! Maybe I can make a deal for my photobooth too...
My 'stay home' cost is no more than my 'out the door cost'.
I don't even have $100 to my name right now. Once I can start making something I can bank most of it but I will likely be investing it on overhead. The lead service for right now, if I decide to use one, is going to be Eventective. Thumbtack was limited to $500 gigs only and that is less than my out the door costs, because I start at $600 and go up with all of my add ons. Not everyone will want my add ons like lights and customized sound, projectors , photo booth, etc; I am looking into facebook ads, I will try it one more time this time without a resaler. I was just asking because there ARE things that to me out of my range. I just can't go out and buy everything and use everything and do it all at once. Most of my DJ related expenses are being paid for from my day job right now, a whole different source. I need to get that fixed so that my DJ money and my living money are two different things. Fixing it is always easier said than done.
