Sunny>> U muz ask the sales person whether himself or herself is the ID~ The ID will sit down with you to go through the basic jobs or services they will be providing at certain price in their packages. So you see the packages are not about your ideas. It's about the essential works that needs to be done for a new unit. As for applying your own style, the ID will draft out designs and ideas by using 3D presentations means based on ur floorplan. They will then align with what you have in mind like themes, specific changes, preferences before going to the selection of materials base on market price and the quality u want. After this process they will list out all the basic package jobs and the additional jobs in a quotation showing how much you'll need to fork out. If you agreed, then they will come out with an agreement for you to sign to award them the contract. That's how the whole part of engaging IDs. Getting contractors is another thing..meaning you coordinate everything urself from calling various contractors companies to compare prices to getting the job done. You won't have the design and ideas according to what you want but only what contractors can offer. But more importantly by getting IDs, you'll need to look out on the conditions of the contract on the type of warranties, job schedule dates and hidden costs..etc. However if you are not comfortable at any stage you can always sit down and try to solve or find a solution with ur ID..and this is some advantage over getting contractors urself. There are always things to take note like I always ask the companies supervisors from which country, how many worker will they deploy for certain jobs and who are their business partner...etc. To me these things are important and I need to ask. So? Have you got some idea about getting ID? If you still in doubt or need clarifications, you call always meet me for a drink and chat session...kekeke~ Actually I went to 5 or 6 IDs recently and compared the basic packages. Cxxxxxx is still giving good promotion packages like free sofa, 10% no hidden costs rebates plus longtime warranties. Then their reputation is big..go their website to have a look or call them to arrange quote meetings. It's free when you give them the foorplan for them to space planning and quote for you~ Their designers are very experience and "quick thinking". In FB..my nick is Dorae Lam~ Call me~
