errr your not doing anything that practically EVERYONE on this forum and in techno has done/is doing anyway. You said it yourself you barely scraped enough cash together to release this, well no offence, but a bit more market research would of fared you alot better, as if you'd of sent these tracks off to say even 30 labels im almost positive that someone would of taken them, and bare in mind there must be hundreds and hundreds of techno labels now. That's just the way it is. Send it to enough people and someone will take it, regardless of the production quality, which to be fair isnt very high here. That's just an honest opinion, and you want to get further in this game then that's one thing you not only have to be prepared for, but positively embrace.
It's time to stop thinking of "im trying to make it, there are so many other dj's etc etc trying to make it"... doesnt work like that anymore unfortunately, just do your thing and if you got true talent then it'l come through and people will notice, just because you have your own label and can produce techno tracks wont automatically put you above other dj's in the pecking order. Maybe 6, 7, 8 years ago... but not these days
you dont have to have your own label and be shelling out money you havent got and scraping around to get things off the ground, it seriously doesnt do anything to help you unless the material is either so well produced that people simply HAVE to stand up and take notice, or its the freshest techno to be heard in years, which unfortunately is neither here. Save the bother, the expense, the hassle and basically the ridicule and find your feet more first. Send stuff out to the plethora of labels currently swamping the market
good luck too of course, but this is a community and community ethos rules here, even if we all do have our differences
