Many people are reluctant to put their prices on the internet, but I see no problem giving a guide. Please bear in mind that this is a guide and not a quote!
Let's say around £250 for a two hour gig as a base price, up to around £500 for a full night. That includes all the necessary equipment (lights, speakers, mixer, digital decks, laptop, etc.) AND a set themed to your needs.
HOWEVER, the price could go wildly up or down depending on what you need. I am based in Inverness, so travel might cost extra. But you might not need lights or speakers or setting up (especially if you are a venue with a sound engineer), so the cost could drop by a lot. Also, if I'm in the area, travel costs will be reduced or absent altogether.
The best thing to do is get in touch.
