Greetings sir,
I have read your project description and have entered a generic (random) bid. We'd need more information here, mainly to see the coding underneath, and to see how much effort it is to make the alterations you require.
To be completely honest, we prefer if we do work initially since we have had opportunities to correct some of the work done by our colleges from India and China, and we could say that our.. erm, approach and schools of programming and development variate notably.
But either way, we are keen to work on this project. If you can provide all the info to access the domain, and take a look underneath, we are ready to get started.
Free Demos are our good practice as to assure you of quality of our work. But in this particular case it would be finished work just unpublished. We are extremely flexible when it comes to payments as we are very confident in work we do. So once the job is agreed, we don't require a dime until everything is completed to your satisfaction. This is an other good practice as to make us a team of choice for the future IT work.
As for our expertise we are 15 European Android / iOS / PHP / Web developers , all experienced in their line of work. Quality, efficiency and reliability is our main goal as to assure our employers are encouraged to work with us again.
If you have any questions, please do not hesitate to contact us.
