Hoping to pamper your pet while you're not around

I currently work from home a few days a week and would love to make use of my time to pamper your pet and make them happy. I live in a second floor flat but do have a communal garden and also Wimbledon common is only 10 minutes away. I have a somewhat flexible work schedule so I can pop out quite frequently and I myself also enjoy heading outside for a walk. My family has always had pets, be it dogs or cats or guinea pigs, and I have always taken care of them. I have dog-sat for friends as well and love the experience. Since I currently do not have my own pet I miss having one around the house so I hope this could be a win-win situation!
