Design me a company logo

Hi, I am soon to be a qualified Domestic Electrical Installer in the UK and require the design of a logo for use on business cards, company stationery, van, t-shirts, ID card etc... The name of my company is 'Techsmart Electrical Limited'. As mentioned, I will be primarily operating as a Domestic Electrician however I wish to convey some level of expertise with newer 'smart-tech / smart home' equipment - hence the company name including 'Techsmart' (Smarttech was unavailable, plus I don't like the 2 't's in the middle of the word). I have seen several logo ideas online that I'd like to incorporate, but want something simple yet effective, not too cluttered and O.T.T. I've included the main element I'm keen to have in the logo (the 2-D house with a cable + plug), plus I'm also keen to see whether the internationally recognised symbol for 'Wi-Fi' can be incorporated (maybe drop the windows in the house, just have a black outline, with chimney and the Wi-Fi symbol eminating downwards into the house from inside the roof apex...? Just a thought... In terms of colours, I've included some of the official logo's that I will be eligible to use on my business stationery etc... once qualified - I'd like a logo that ties in or complements these colours please, and I'm also keen to incorporate the colours 'blue, brown, green and yellow (latest colours for UK domestic wiring) as a series of 'underlines' beneath the logo and the company name i.e. the logo underlined with the 4 coloured stripes (please experiment with all combinations of the 4 colours). I was envisaging the logo being to the left of the company name, however happy to consider any alternatives. I have also included a shot of the logo belonging to the company whom I have trained and qualified with as I quite like the simplicity and effectiveness of ther brand. Finally, within the logo or within the company name 'Techsmart Electrical Limited' I'd like to incorporate the element that can be seen in the attached 'CPN CUDIS' logo (whereby the blue box around 'CPN' and the 'D' of CUDIS have made use of the standard electrical 'switch' symbol. I'm also happy to see ideas that may incorporate other standard electrical symbols that 'work' with the overall theme, although simplicity and not references to anything electrical at every opportunity I think is key. I haven't included in the upload document the industry standard electrical symbols as these are readily available on the internet - I do like the CPN CUDIS use of the electrical 'switch' symbol purely because of the simplicity and the recognisability of it. Of course, I'm no designer, so I'm also happy to review ANY other ideas that are deemed appropriate. Many thanks John
