You have done really well to get this far. Your website does need a quick read over by someone who hasn't seen it before but everyone's first attempt is the same. In the future consider dojo interactive in Congleton. They are very professional and deal with some high profile clients but don't charge extortionate prices.
Again you have done very well to make it this far. good luck finding clients and I would advise you that when taking on new contracts always ensure you go above and beyond what is expected. If you are given a 2 hour clean consider staying on that bit longer to do some extra little bits.
Many cleaning companies go in do their hours and leave with out leaving that WOW factor. I wish you all the best and good luck with your venture
