Well I'm still learning the trade and need to put more practice in but should get good at some point.
I charge Â£25 per track up to 5 then Â£15 after that.
Any tips on how to promote the service would be really great at the moment I am on Google Adwords though it is not cheap.
I can cut it maybe takes me longer than most to find that sound down to the tea.
Would also like to ask do Engineers really need Monitors to do the job or will a decent pair of PC speakers be any good or does all of come down to the persons ear no matter what setup.
My experience in Marketing may be able to help you here...
Google AdWords doesn't generate sales unless you have a reeeaallyy detailed plan. Especially for this niche market. I'd suggest not going down that route unless you have a perfect digital marketing strategy (not to mention analytical skills to actually see where your ads are being read and when etc).
You should first assess what stuff do you have? If it's only a cracked version of Ozone, some KRK's and EQ8 then I'd probably readdress that setup. Mastering engineers need the best audio products possible, with at least an outboard graphic EQ. And no, PC speakers will not be any good. If you start finding monitors anywhere past Â£700 then you may be on to something (Brian Sanhaji has Â£14,000 monitors...)
You next need to go to labels, showcasing your services. That is, do some EP's/Albums that get a ton of decent feedback and then use that to promote to them, showing how you can help get the same level of support for their releases. This should take months (it's not a quick buck...)
Going straight to artists isn't advisory. I get at least 2 of these adverts a month and I bin them pretty much immediately. You might want to check out Sleaze Records who use BCR's Jo McGeechan. That could also be a possible route to go down.
Hope this helps.
