hi, i'd consider renting a chair more than going mobile. Going mobile can be hard work, finding the houses, trying to park/paying for parking, getting all the equipment packed up and carrying it around with you.. renting a chair is a much better option in my eyes. A lot of places you can rent part time and choose your days/hours, therefore fitting in around your child and your job and you don't have to carrying everything around or eave extra time for travelling.
